I need a new wiring harness that goes from the ECU into the engine bay, but I'm confused about the part numbers and want to make sure I'm ordering the right thing. I Googled "99-00 Civic Si wiring harness" and found this thread:

https://honda-tech.com/forums/honda-...rness-3157081/

The part number given in that thread (32200-S04-A52) sounds like it could be the one, but the price seems a bit low. It's listed as "Wire Harness, Engine Room," but others seem to contradict that within the thread. Could someone look at this link and please let me know?

I have a feeling it might be the discontinued part 32100-S02-A42. Thanks for the help.

 

Interesting question.

 

The proper part number for a '99-00 Civic Si engine harness is 32110-P2T-A00 , however, it is discontinued and no price is given through the online Honda parts system. You will have to call your local Honda parts department and ask them to do a full system search and cross your fingers. If nothing comes up, check vintage parts.

Good luck.

 

Thank you! I don't know how I missed that there was another category. Looks like I have to get a used one. Amazon sells them, but there's a 1-2 month wait.

Sorry about the cross post, but I was trying to increase my chances of getting a quick answer.
