Boost/Pressure Sensor Mod: Wire question..
Hey guys. I was following AaronCake's writeup on engine grounds, but I just had a quick question. It says to ground the brown/black wire (for '86-'88 cars). I don't have that one.. So I'm just assuming that the black wire is my ground, even though it says it's for '89-'92 cars. Mine is an 88 by the way. Is this correct? I just wanted to ask before I grounded something I shouldn't have.

according to ECU pinout, PIN 2C is GROUND on ECU and connects by B (Black) wire to pressure (boost) sensor
I have same colors like yours on S4 car and i am going to add ground to Black wire......
Black White goes to ECU pin 3L (Main Relay)
Brown White goes to ECU pin 2A (V-Ref)
Brown Red goes to ECU pin 2B (Boost Sensor)
