I installed a stock boost gauge and a pressure switch and wired it per the TEWD (although not clear). I used a JZA70 cluster to figure out the connections for the drive circuit. I had to cut the printed circuit board so that I could make the connections (the cluster is from a N/A). I read somewhere that the boost gauge will only work under load, i.e. it won't work when the car is in neutral and stationary. is there any way to test if it is working without driving the car? If someone has a close up pic of the connections on the back of the MK3 turbo cluster it would be greatly appreciated.
Cheers
