Difference between S13 & S14 wiring for a redtop?

[90rps13]

I will be receiving a redtop swap soon out of a US S14 chasis and will need to convert it into an S13 body. Is there a big difference between them? Please let me know, I already searched and came up with nothing.
Thanks in advance.

the red top harness is fairly simple to modify to work in the s13. doing some research on SR swaps should give you wiring info.

...but.. because you're getting an S13 motor, wired to work in an s14, and trying to convert it back to s13, things could be a little complicated. it really depends on HOW the harness was modified to work w/ s14 chassis. (the main differences between s14 and s13 is s14 windshield wiper harness is integrated w/ engine harness, and a few relays and conections are under the dash on the s14 as opposed to the engine bay in s13... plus some other shit...)

Here's a great site for installing you motor:

And here's some info on one way to modify an s13 harness to work in an s14:
nevermind, it seems my old resources links don't work anymore... but i'd do a search on s13 SR into S14 body, to give yourself an idea of what you might see......
