Default Harness>ECU Help

Hello HT I have a problem that I myself cant fix because Im more of an engine person...

I have gotten a new harness for my Civic (Right harness, already confirmed) and everything plugs up but when I plug up to the ECU in the car the plugs dont go where the wires are heading. Anybody thats really good at this know a fix? Its my DD so Im in need of speedy repair here. Thank you in advance.

Heres a pic, sorry if its oversize.

one of your harnesses is wrong. i assume you have a 96-00. you appear to have an obd2b engine harness. your jumper harness is for obd2a. you're also missing the connector from the dash harness.

Its plugged in. It just wasnt in the pic.

And to Jimster im using a P28 ECU and in the pic the wires that run to the central plug-in area from the ECU doesnt match with the harness, besides the blue plug. Hell my last harness had three plugs instead of two. Just wondering if theres a nice cheap fix. As im not very financially secure.

is your car a 96-98 or 99-00? if you have a 96-98, you have the wrong engine harness.

if you have a 99-00, you have the wrong jumper harness.
