View Full Version : SR20/KA S13 Lower Harness HELP!

Solved! See below.

I realized that the SR I have did not come with a transmission harness. No biggie as most say to use the KA Lower harness anyway. So, I went and bought a KA Lower Trans Harness, printed out diagrams of both harnesses, but I still can't figure out where everything goes!

Does anyone have a diagram for an S13 swap? What goes exactly where and what's not needed? I've looked everywhere.

Below are some pictures, labeled with what I know and don't. Appreciate any help! It's the only thing holding me back!

Cracked open the S13 FSM an hour ago and figured it all out! Now I know what I can rid of, so I have a nice tucked harness. Here are the above images, but with the right places to connect them. Figured that it might help someone else too.

I assume this will only work if you have a manual ka lower harness

The black ground wire in the second picture goes to the back of the alternator, NOT the starter....

And also the white wire with rubber boot goes to alternator, NOT the starter.

I hate to revive a dead thread but I really need to know, did you say the 4th, 5th, neutral and reverse plugs aren't needed because you are installing these on an sr20? I;m trying to figure out if I need these sensors on my KA. Help please.

sr20 dont need this plug, but with the ka im sure you do or else they wouldent put the connecters on the ka harness [not being a smartass it sounds like it though ha]

KA/SR sensors are the same they just have different plugs. You can either throw the KA sensors into the SR transmission and use the KA harness plugs, or buy an SR lower harness, or cut the plugs and wire them directly to the harness.
