Have you got wiring diagrams for both cars??

I haven't done an SR20, but like quite a few people on here I've done my own 4AGE, and the basics are all the same.

Are you planning on using a COR relay box from a Nissan, or making something up from scatch??

You should have all these plugs, and life will be easier if you also have the plugs that go into these.  So the chassis loom with wires cut off 100mm long. I used stacks of junction strips which was simple to do and I planned to replace them with neater wiring.. sometime.

Then you'll need a full engine wiring diagram and ECU pinout to find out which plug goes where and does what.

You will end up using relays to run fuel pumps, electric fans, & powering ECU stuff. I ook a COR relay box out of a random Diahatsu & used that for circuit opening relay, fuel pumps, engine fan & whatever.
