Getting the correct engine harness has been a headache. Getting into this swap business at this time has been interesting. A lot of information I'm finding is dated or spread across multiple posts.
I need to source an engine harness for my CRX K swap that I'm attempting to complete. I have a k24a2 engine and an RSX 5 speed manual transmission '02-06.
I picked up the PND-A08 '02-04 RSX ECU.

From what I can gather, I need to match the ECU, so that means sourcing an '02-04 harness from a manual RSX. This is what I want to double check.
A used harness from Ebay is $300 whereas a premium from other sources easily exceeds $600. I want to do this right without necessarily breaking the bank where possible. I have more time than money at the moment. Should I spring for the $300 used harness or can I potentially source a cheaper harness from a different Honda model? One of my difficulties in this build is that my local junkyards are few and small relative to other cities.
