Wiring Battery Plugs? SR20DET Harness

[rpierce]

I have a redtop SR20 engine harness I'm going to use for my swap, but the importer decided it would be a good idea to cut it where it plugs into the main power/fuse box. The part circled in red is whats cut.

It seems like it could be fixed with that section of a KA harness since the plugs are the same, but I can only assume the colors of the wires are way off. After searching for a day or so I've found a few wiring pinouts but they're mainly for the wires at the ECU plug and a lot of wires are the same color so it's pretty confusing.

I know this is asking a lot but would anyone happen to have a diagram for the wires to the power plugs for the KA and SR harnesses?

Thanks in advance.

Well, when I did my swap I followed frsports wiring guide
SR20DET Swap Engine Harness Wiring Diagram Guide SR SR20 (http://www.frsport.com/SR20DET-Swap-Engine-Harness-Wiring-Diagram-Guide-SR-SR20_t_26.html)
Look at figure 5a, what I did was used my stock ka engine loom plugs, cut and soddered there so I can remove if necessary. The wire colors are listed right below the image with both sr and ka colors if you have an s13... Goodluck

Oh I completely forgot about that page on FRsport, thanks. Since I don't have the original plugs and I'm going to be running A/C I guess I'll just have to guess which green and yellow wire is for the AC relay unless I want to deloom the whole damn thing and trace it back.

Hopefully if I hook up the wrong one at first there's nothing that can go wrong.

One is for the o2 power others your ac... Shouldn't matter as they are both a switched power but I'm really not sure on that but I thought mine only had one green and yellow wire. I didn't put ac on mine so it was no issue. Also I had a 90 which has the ka24e in it, and the wires were a tad different than that guide.
