Hey guys.....
So I'm doing a swap and I'm pretty good at doing the M20 swaps etc....this time I'm doing the S50 OBD1.
Well, I got the donor harness out of an E34. Now everything is straight forward except the extra wires that are present by the 3 relays? Matter of fact, the connector is on the same rail holder as the relays. The fat red wire is obviously constant power, but the others I have no clue? Wires are integrated into the harness too....so I def need an answer
If you go to my build thread, you'll see what I'm doing. Go to the last page....M20 took a dump
The plug on the right?
