I have built a bench harness for a spanish oak controller from a 07 police interceptor. I can not get it to read or scam with any tool. I have the three 12v+ wires on controller wired up (pin 35. 36. 45} and the grounds wired. The two can wire {11, 23} and the feps wired to obd2 connector. the obd2 connector is wired according to print, 16 12v+, 14 can-, 13 feps, 6 can+, 5&4 grounds. i have tried mutiple pcms and can put pcm on car and it reads. I am not really sure about the operation of the feps wire. I have read that some say you have to put 18vdc on it to get it to read. But if this is wired as it is on car not sure why I would have to do this if you dont on car. On the cae I dont read any voltage on feps wire with scanner hooked or unhooked. I have built several bench harness before but for gm controllers. There dont seem to be near the info out there for these compaired to gm. Does anyone have any ideas?
