Hi name fellow Zilvian's,
So I finished swapping a late model S13 blacktop with a J4 ECU and wiring harness. I tried to match up my wires at the battery as best I could but my SR harness has some wires that are different color than the what the car has. all the write ups say to just match the colors, but like I just stated I have some that are different.
This is the info i do have,
1. fuel pump turns on
2. o2 sensor gets power
3. tomorrow morning i'm gonna check for spark and see if the ecu is getting power.
If anybody has successfully install a j4 ecu and oem wiring harness please let me know how to do this correctly.
