been looking at a lot of wire tucks and jobs. looks very nice. it got me thinking about my wiring harness and how its all jacked up. i have a 98 b18c1 in a 98 civic dx hatch. i running either a usdm p73 or jdm p72 ecu. my jacked up harness consist of mainly the 98 harness with sliced in missing components for the b18c1 (vtec, secondary, couple other things i cant think of atm.) now i was thinking of getting a 99/00 civic si harness and redoing the harness so it would be a perfect fit for my car. probably going to rewarp it in some nice wire loom, or the shyt that rywire or chase bay uses.

my question is what do i needa to add on the engine side of the harness for a 99/00 civic si harness so it would accommodate an odb2a b18c1 with skunk2 IM. for the ecu side, i figure it would be just be depinning the odb2b plugs and matching/repinning to odb2a plugs. is there anything i needa to add for the ecu side?

basically odb2a 98 b18c1 with 99/00 civic si harness into 98 civic, what i needa add?

bump for some help?

A SI/EX has no secondary o2 sensor wiring built into the engine harness, its built into the cabin harness.


I reccomend you use your stock harness, wire in vtec and vtec pressure switch and knock sensor. If you solder/tape/loop all your connections and add on's, you have nothing to worry about. Redoing that harness and saving alot of money as well would be your best bet.

If you run a skunk2 IM, you dont have to wire in the IAB.
