Hi there, i got a '89 TT z32 prolly bout 6 months ago - and only until now have had a chance to actually work on it. The first thing that I wanna get done is the turbo timer - and when I purchased it - everything was installed but i think it seems to be now power connected to the unit. I have had a look at the wiring, but cannot figure out wat is wat, was wondering is anyone has any idea on finding how to turn it back on? its a HKS timer. Any information would be great.
