Wiring harness question

[CMoon93]

ive recently bought a 93 240sx that has been gutted.. i have a sr20det swap thats going in this coming week and i cant figure out how to get power to the pcm to run the engine. ive looked at many diagrams of the sr20 wiring harness and cant find anything as far as what wire powers the pcm. any help would be appriciated...

This is probably no help, but if you looked at so many diagrams and can't find where the power for the ecu come from, you should probably stop.

Don't be offended, it's just because I would be basically be telling you what I've read from the FSM's which has diagram's and doing a quick search right now brings up more diagrams of where the power for the ecu comes from. Then I look at your post count. Sure, you took the time to search? You just can't read diagrams.

But the answer is the eccs relay, then you say where does the eccs relay get it's power from. See that wasn't really worth you not really searching, was it? ;)
