I am trying to hook up an o2 simulator and I cant figure out which wires are which. Does anyone know which one is the signal wire? I also just put some Eibach springs Prokit and have all of a sudden started expieriencing problems with my brakes. Every once in a while the pedal justs drops. I found my driver side banjo bolt was loose. Wierd because I never touched my brakes when I put the springs on. But anyway I replaced the gaskets and tightened it back up and bled the hell out of all the wheels. But once or twice a week the pedal still drops. What do you think?

 

green wire is the signal wire. white wire is the heated + lead, both black wires are ground for both ckts. as far as the brakes, are they spongy at all? once it does drop, if you pump it again does it regain pressure?

 

Thanks I got the simulator hooked up and the light stayed out for about 30 miles and then came back on. I haven't got the code read yet but it seems like it has a slight engine miss. Who knows? Why did everything start falling apart when I put the springs on. As far as the brakes they feel fine except for that every once in a while pedal drop. If the pedal drops then yes I can regain pressure usually with 1 pump. Also I just ordered some 17x7 rims. What size tires do you think I should go with?
