Question about sr swap

[koolcat]

Hello, im on the process of dropping the s13 blacktop in my 92 fastback. I have a question about the wiring harness though, I received everything from the seller but how do i know if the wiring harness is for my j4 ecu? Also, can i just follow the diagram on here?:
SR20DET Swap Engine Harness Wiring Diagram Guide SR SR20 (http://www.frsport.com/sr20det-swap-engine-harness-wiring-guide-sr20-p-665.html)

Thanks in advance

There are a lot of threads on here that can answer this for you, I used the FR sport guide and Heavy Throttles to get me through it. here's a link Heavy Throttle (http://srownersclub.com/faq/index.asp#ecuwiring)

how do i know if the wiring harness is for my j4 ecu?


there should be a tag on the harness that states what ecu it is for.

See that is the thing i am confuse about, since i figured out i have one of the 4 j2/63/e5/e6 harness, do i just repin it according Preparing to put in new wire harness. I have a few questions w/PICS: SR20DET Forum (rear-drive): Nissan Forums / Infiniti Forums - NICOclub (http://forums.nicoclub.com/zerothread?id=297604) to converted to a j4 harness? After that can i use the same wiring as Heavy Throttle (http://srownersclub.com/faq/index.asp#ecuwiring) or SR20DET Swap Engine Harness Wiring Diagram Guide SR SR20 (http://www.frsport.com/sr20det-swap-engine-harness-wiring-guide-sr20-p-665.html?) thanks so much

Oh mine all faded away so you can't tell, but i checked the diagrams for both ecu for Preparing to put in new wire harness. I have a few questions w/PICS: SR20DET Forum (rear-drive): Nissan Forums / Infiniti Forums - NICOclub (http://forums.nicoclub.com/zerothread?id=297604) and found out i have the one that is not for the j4
