Re: ca18det+ka lower harness
fortunately i got ca lower harness when i got my motorset.
99% of your wiring questions can be answered here:

Wiring diagrams for an s13 SR swap are nearly identical to our CA swaps. Use them first, and if you still can’t get it, start a thread asking EXACTLY what you need to know.
The only main difference between the CA and SR swaps is that sometimes the wiring for the knock sensor isn't present, since on the CA it runs through the body harness and on the KA and SR it's in the engine harness.
how to use the KA24E/DE lower harness on CA18DET (for the s13):
All the plugs will plug in just fine; none of them need to be extended. Just don’t worry about the 4th and 5th gear sensors. You might have to rewire the reverse sensor plug, or swap the reverse sensor from your KA tranny to the CA tranny. You should also swap the JDM speed sensor for the USDM speed sensor if you are using a MPH cluster, or else your speedometer will read incorrectly. For the starter, the KA and CA have completely different positive terminals (the lowest one). What you can do is cut the plug off of the ka starter, and then plug it into its appropriate spot on the lower harness. Then you attach that to the CA starter plug using one of the crimp style connectors. For the knock sensor, just solder it onto the plug if you have it. If you don’t have the plug, you could solder it right to the sensor. Then find pin 23 on your ECU, and splice your wire into that wire. Use shielded wire! You can take some from the KA harness.
