why does the rb20 wiring harness only have 3 injector connections on it , is there a seperate harness that connects to it and the other injectors?

 

no the harness is all together should have 6 all inline.

If you take the harness apart they will then break down into two sets of three.

 

thanks alot for the info man I have now taken apart the harness and seen that it has been previously stripped . I am missing the #4 , 5 , 6 injector plug conectors and will need to find them. Any idea where I would start looking>? other than orderin from nissan..

 

They are standard top feed clips you can get them from a KA24e/CA/RB26/ harness and wire them in. just be sure to wire the signal and resistor wires properly.

 

Wiring Specialties makes premade RB20 into S13/S14 harnesses n u can buy a new one with all 6 plug n play ready. I got an entirely new harness from them. Engine, trans, and coilpack harness n u can get them seperately
