I need to know which pin from a p28 ecu has ignition power to the main relay!?

 

A25 goes to the Main Relay and Ground...as far as an ignition power source, A7/A8 or it might have its own +12v source that doesnt come from the ECU.

 

The previous owner had told me that he needed to jump ignition power to the relay because the ecu was damaged and did not put out the ign. power to turn it on! I asked if he remembered which pins they were or even wire colors, and he said he'd get back to me, still waiting!

xenocron- thanks for the help, i'll look into the pins you described.
