First Post, take it easy on me.
I race a 96 integra on a dirt circle track. Just purchased a H2B swap engine to put in. Seller gave modified wiring harness he used as well. Engine was in a civic.
My problem is the harness has no connections that plug in to ECU? What am I missing? I need some kind of jumper to go to p28 ECU. This is plugs on harness.
Thanks in advance!

 

The engine harness on a '96 Integra plugs into the chassis harness at the shock towers. The ECU plugs are found on the chassis/dash harness and not on the engine harness. If your current engine harness has the ECU plugs at one end, you have an aftermarket engine harness and not an OE one. These are common in round-track race cars. In that case, you will likely have to modify your existing engine harness to fit the new H series engine.
