Hi guys i have a question my ca18det came with lower harness but they were cut to the chassis side my question is can I solder the wires with the same color and be done with it?? they're for the starter, altenator and knock sensor


Here are the lower harness cut from the engine

You might have trouble soldering the wires due to their size. You may be able to get crimp connectors big enough to do it. Put complete runs of new wire in if you can.
As for the knock sensor, this is a shielded cable that's trying to carry an analog signal so soldering it back together isn't ideal at all.
Hope this helps.

Is this a JDM CA18DET going into a USDM S13? If so, there is no provision for the knock sensor in the stock chassis harness and you have to run it into the CA18DET harness, you can't go through the stock S13 chassis harness.
