Hey I'm having some issues with an rb25 swap I'm doing.
The car is an 89 s13. It has a KA24e harness in it. The harness is the problem I've run into.
I understand on the 8 step guide there is a brown plug. I know this plug is actually white on the SOHC harness however three out of the five wires are not on this plug. They run from the blue ecu plug on the KA harness out to their respective places on the chassis.
the BLK/PNK at pin 104 (fuel pump relay)
the RED/BLK at pin 4 (ECCS relay)
the BLK/RED at pin 36 (ignition switch).
It's lead me to the issue of no longer understanding how to splice the rb harness into the ka. I'm stuck and am not sure how to proceed. I've done a lot of seraching but can't seem to find any info on this particular bit of wiring. Any help would be greatly appreciated.
