How to correctly send us your wire harness

 

The fastest and cheapest way to send a wire harness is with the Post Office. If you live outside of the USA, you will more than likely have to fill out a customs declaration form, this process is quite simple! An important note: you are not selling us these parts, rather you are sending them for repair and to be returned! So when filling out the form simply write: Automotive wire harness sent for repair, no commercial value. In the value field, put one dollar. In the insurance field, insure it for whatever amount you feel comfortable with.

To help us plan our time around the arrival of your harness please forward the tracking information to our email.

If you insist on sending with a courier such as UPS / Fed­Ex you will be 100% responsible for all fees incurred.

What happens when the harness gets here?

Before starting the harness we will email you to ensure both parties are on the same page. If there are any missing parts or concerns that we may have with the harness, this will be discussed before any work commences. The harness will be sent back and labeled as a “repaired automotive wire harness.” Again, if you have any questions or concerns, please let us know!

Davids 81 Scirocco

David called and said his 16v was making some “extra” noise, which he believed to be a rod bearing that took an unscheduled leave of absence..  David is from the great white north and had the car shipped down to us to look it over and try to come up with a game plan for his best options moving forward.  We weighed rebuilding the 16v, adding modern fuel management, even forced induction.  After several conversations about options he actually decided that a VR6 would be a nice mid ground to having a NA car, with modern injection control, and a fun to drive powerband.

So I got to work:

Ok, so I had to take advantage of the fact there were 3 red roccos here at the same time..

Now I really got to work…

With the old 16v out, the bay had a few issues from previous owners, while I do not sell myself as a paint and body shop, I will make repairs and spray an engine bay for a customer.

Back side of the repairs seam sealed and ready for service.
With the holes fixed, the bay was ready to paint.

A new coat of paint goes a long way in an old engine bay.

Onto getting the new driveline ready, I had an 04 touareg motor with under 80k on it.  With a touareg motor into a tranverse chassis there are a few pieces you need to swap from either a 2.8 BDF or mk4 r32 motor.  Oil filter housing, oil pump and pan,  exhaust manifolds, accessory bracket (if you want to keep AC, otherwise you can use the treg bracket and accessories) lower timing cover needs to be ground down to clear the trans.

As a rule I always replace service or wear items on a motor before I install it,  so this motor got chains, guides, rear main seal, plugs, coil packs, waterpump, water transfer pipe, thermostat housing, thermostat, valve cover and manifold gaskets.

With all of that done, I was ready to fit the motor.

As you can see the radiator is in before I fit the motor, I cover this in our install videos but this gets overlooked more often than I’d like to hear about.   I am using one of the S&P Mk1 Vr6 radiators with a single fan and a 70c fan switch.

David insisted that we find an Audi intake manifold to dress the motor up a bit over the boring Touareg manifold,  good call on his part, looks great on top of the VR lump.

I knocked out a hidden MAF intake, a remote fill bottle for the coolant system which finished off the plumbing to the radiator and heater core.  These along with the valve cover and upper strut brace got a wrinkle black powder coated finish from TopNotchCustoms located here in town.

Onto wiring,  as with many of these cars the wiring had been touched by alot of people, and they all left their mark..

I removed a lot of the old management wiring, some was even left from the 81 motor that was long gone,  there were abandon relays, multiple wire taps for radios or accessories at some point.  All of it needed to go and start with just what was needed for the current setup in the car.

With the interior wiring in a better place, I moved onto the battery which was moved to the back, using an S&P Battery Box I mounted the Optima Red Top into place with a main breaker mounted on the box itself, this prevents having a 2ga torch running the length of the car if you have a short between the battery and the fusebox/starter/alternator junction point.

The original headlights were tired, I installed some LED low beams and h4 high beams with a pair of Hella relays to keep the load off the switch, this also gave me time to put the face back on the ‘rocco.

Time to get under the car and install the exhaust system. Using a 2.5″ stainless kit from TT with a Borla muffler gets the VR notes out in the perfect way without getting that drone while cruising the highway.

Onto suspension brakes and bearings, I installed a set of Mk1 Solowerks Coilovers  along with new bearings into the ‘rocco spindles, the car was already setup for 10.1″ 16v brakes so just a hardware refresh was needed there.

The seatbelt retracts were sticky, and unresponsive so we sent them out to Safety Restore and had them install some red belts for a bit of color on the inside, David once again was right, it looks great without being LOUD.

With all the safety issues covered it was ready for some road tests.

Driving Video

I was able to take it to a local show before it had to be loaded up and head home to the Great White North.

This has been one of my personal favorites, its not overstated, its not slammed beyond function, its a ton of fun to drive (yes even in the corners thanks to sway bars and reasonable ride height), it sounds great, it looks good enough to be brought to any GTG or show, but doesn’t have brand new don’t touch me with anything but a diaper paint.  Overall a well sorted car, I hope David gets many years of enjoyment out of it.

Bruce’s Black 84 GTI

 

Bruce wasn’t a euro guy, that was until he happened across an 84 GTI that needed some love.  Unfortunately some shady people took advantage of Bruce’s good nature and after starting on a 1.8t swap, his car sat and alot of the parts were “missing” .

He brought it to me and after assessing the missing parts, and the general state of the car he decided that he would rather start over with a different driveline and settled on a 12v VR6 that I serviced up with new chains, guides, ignition wires, plugs, new gaskets, fresh clutch and then bolted the S&P Vr6 hardware kit to the VR lump and set it into the mk1 shell.

The car also got a fresh set of 9.4″ gti brakes, a full set of Solowerks Mk1 coilovers and strut mounts.  We cleaned up some chassis wiring issues and sent it home with Bruce, he says he enjoys the look on mustang drivers faces when they cant shake the little mk1 econobox..

A few pics of the install below..

VR-lequin

S&P’s take on a VR6 Harlequin.

Almost everyone has seen one, whether or not they knew it was a purpose built car and not an accident, who knows…

In 1996 Volkswagen built a small batch of cars for a promotional purpose. They were built on a 4 door Golf GL chassis, the only real interior difference was the seat upholstery, it was the same fabric used in the “joker” trim on European models of the same era.  The outside is where the “magic” happened, VW took panels from 4 base color cars (Red, Blue, Green and Yellow) and swapped the removable panels between the other base color cars, leaving you with a very loud exterior.

 

Fast forward to 2015, and I have an opportunity to buy a very sad, yellow base harlequin locally.  It had been resprayed at some point to be all yellow, but the colored panels were peeking through the worn paint.  The driveline was tired, the interior was beyond tired, it was time for either a restoration, or euthanasia…

I sent the car off in pieces to my local painter, he began smoothing out life’s abuses and owners neglect, fixing shopping cart dings, and poorly placed jack stands.  We needed a new hatch, or at least a tub that wouldn’t fall out every time you closed the hatch or went over a bump.

I found someone parting a 4 door golf, that had a lot of Euro market parts, hatch, bumpers, core supports, rebars, etc.  We took it all.

Next on the list was the interior, after looking and not finding anyone wanting to sell their limited edition seats, I spoke with Kip at Loves Trim Shop and worked out a plan for some new threads.  Mk2 Recaros on mk3 bases, leather wrapped, suede inlays and stitching to match the colors outside, without making the interior too loud to enjoy driving it.

That left me to get started on the driveline, the stock ABA was no different in the harlequin cars than it was in a standard Golf GL.

I had a 2.8 24v from a GTI that was wrecked, I had the machine shop go through the block, hone and a ring job, new bearings, new chains, guides, gaskets etc.

I couldn’t help myself, since I had it all in pieces I painted each section of the motor in the matching colors of the car, engine block, head, upper timing cover, lower timing cover, valve cover, intake, accessories, brackets…
I was seeing spots from all of the painting and planning.

Now that the car had been painted back to its original colors, engine painted and assembled and interior back from Love’s, it was time to make it a whole car again.
This is always the fun part, assembly is very gratifying.

Since the interior itself wasn’t very “loud”, Brandon Rosensteel at EuroGlow made an overlay for me.

Once the car was fully assembled, we could enjoy the best part of a vr6 swap – DRIVING!

During this build, a lady had contacted me about wanting to purchase the car when it was done. That is another story all together and arguably better than the one I just told you.
She and “Polly” now are in the Knoxville area, so if you see them, say hello!

Matts 1981 VRirocco

Matt wanted to be able to jump in his Scirocco and drive it everyday, without worrying about the failing CIS system leaving him on the side of the road.   To overhaul the 1.8 and rebuild the CIS system was a realistic option, however after looking at the cost of the rebuild he realized he was well on his way to a later model motor swap.  Even better.  Better mileage from an 02 controlled fuel system, more power, easier to find parts. Win-win!

On to the evidence!!

S&P Radiator and Intercooler Stack

We shortened up our dual pass radiator, and made it stockier, 2.5″ thick core, so that we could put a 21×2.5×3″ intercooler core on the top of it.  Now we can add a condenser to the front if we need to, or tuck it all the way under the core support and make some room for that 1.8t log manifold.

We should have this ready for shipment by mid to late February, we are sorting out the last bits of attachment points, testing outlet sizes and making piping kits for 1.8t and TDIs

Keep your eye out for a purchase date!

SHAWWTYS ARE HERE!!

Look at that, a radiator that fits UNDER your core support, now you can tuck it out of your way.  Great for CARBS, ITBS, or even the big VR6 swaps..  We have a special shroud for these radiators, and as with our other radiators, they use the stock fan switch, and factory size coolant inlet and outlets.

Grab just the radiator HERE
