Grounds and ECU
 

Hello everyone,

I rebuilt my engine and yesterday I put everything back in the engine bay. Everything went fine except that I had two grounds, which I forgot the correct location for. I checked the forum an vaguely found an answer. However, when trying to connect the battery, it sparked and smoked at the terminal.

When disconnecting those grounds, it worked fine and I could put the car in accessory mode. I did not try to start it yet, I need to readjust the TPS first.

Now I have two issues.
1) Where should I put those grounds?
2) My pfc commander does not turn on, could this have fried the ecu?

Ground in the front harness

Solved it, first ground connects to the egi fuse box, second one to chassis
