Does anyone have a picture of where the 12v is hooked up? I did a search and found a lot of info, but I would like to see a picture of how it is hooked into the fuel pump relay. I am ready to install it, and I dont want to screw it up. I have three relays in a row, is it the middle one? Even a good drawing would help.
Thanks

 

Your right about it being the middle relay. I connected mine to the grey wire when I was running a heated O2 sensor. I've read where you need one if you have headers, but after driving with it for several months, I decided to replace it with a regular one wire O2 sensor. I really didn't see any difference in performance. I know it is suppose to get the engine in closed-loop faster, that's just me. Best bet is to double check it with a voltmeter.

 

91B2L, do you have headers? I have long tubes, and the car is running terribly rich.

 

I'm running Edelbrock headers. A month after I installed the headers, I got a code 44, I think that's running rich. I went both ways to cure the problem. First, I got a Holley adjustable fuel pressure regulator and second, the three wire O2 sensor. Not sure which one cured it? Most likely the afpr helped out more. Sorry, not much help.
