Wiring harness help!

[Jon-S14]

I have a lower engine harness that was cut. I have plugs for starter, alt., oil pressure switch and the 3 left for the tranny. I got another cut harness with a Positive battery cable I believe on it and there are 2 plugs and 2 fin plugs within the same harness. Could someone please piece together what these plugs are for?

positive terminal/2 small plug,alternater+/- plugs,starter +/- plugs,nutral sensor plug,reverse sensor plug,speed sensor plug,i think thats all the lower harness should have,let me know if im right or wrong.

Sorry I forgot to mention that this is a S13 Blacktop sr20det motor. Are there any differences between the blacktop lower harness and the redtop harness?

[IngS14]

basically the same just different plug sizes on the sensors.

hey you can just use the harness from your old ka motor. worked for me because my harness was cut and messed up.

Exactly, I find it easier to use a KA lower harness. Just take the KA tranny sensors, put them in the SR tranny, plug up the KA lower harness. Done.... and done.

So all the specs from the ka sensors is the same for the SR.... That would make life a lot easier! Thanks guys!
