WIRING an ls1 into 240sx i'm almost done with my ls1/t56 swap into a 1992 240sx coupe. i have searched and could not find anything that is ls1 and 240sx specific, i have heard that there are 8 wires that are needed to get the ls1 up and running in this chassis. i dont even know where to start with the wiring harness. If anyone could help me it would be greatly appreciated since this is the last thing holding me up other then exhaust.

post #1 and the attachments in post #13 for more wiring info. that will cover all the ls1 info you need to know.
sent you a old pm i had to give you a little help. but i didnt know about the F3 plug at the time of my swap so you can do it better then i did. but mine works great.
if you can find the pinout for the F3 plug on the s13 that you help you alot. i only have the s14 pinout.
BTW; the F3 plug is right by the 240sx stock puter location.
