air/fuel ratio gauge install help on e34?
Hi, I have installed a nitrous set up on my e34 with the M50 motor. I need to find out how to hook up this AFR gauge that I baught so I don't run the car too lean and cause detination. If any one can help I would be greatful. The gauge is suposed to be hooked to the signal wire from the o2 censor. I tried atatching it to each one of the wires and had no positive results. I replaced the o2 censor thinking it was bad but no luck. If anyone knows what wire is the right one and where it is please let me know. Thanks
