I am wondering a if anyone could tell me what wire it is that powers the efi computer on my 88 f150. I need the wiring color and if possible the pin number at the computer connector. I was also wondering if anyone could tell me a good way to get my fuel milage better. I know it has to do with the o2s, I just replaced it and my mpg is better, but the right exhaust pipe looks ok (this is the pipe the o2s is in), but the left pipe is sooty black, which I think has to do with the fact that my efi is not monitoring that side like the right since there is no o2s in that side. Any ideas on how to get the computer to read both sides effectively be great. Thanks!
