These adapters are great if you are a mk1 owner with a mk3/4/5 swapped chassis and are needing to keep that mk1 cluster working perfectly.. Simply install this in one of the spare locations found in the coolant system, attach the included ground wire, thread your sensor into the adapter, attach your original signal wire and boom, a working mk1 cluster again!
They also work for aftermarket gauge installations for the mk3/4/5 owners, install the sensor into the adapter, ground the adapter with the provided ground wire, install into the coolant flange, enjoy an aftermarket gauge in your cockpit!
Here is our “magic” box !! Its a dual purpose unit and has 2 modules in it, digital>analog + cylinder conversion. It’s used for many applications, putting a VR6/1.8t/TDI/2.0 into a mk1/2 and retaining your factory cluster. (However if you wanted to drop an ls1 into your mk1 and drive the stock tach, this will do it for you)
This module will allow your factory cluster to read the correct rpm of the engine. It will save time on not having to do a dash swap or retrofitting the 6 cylinder cluster and allow you to maintain that stock sleeper look inside your mk1 or mk2.
