I'm swapping a 99 B20Z into my 93 Si hatch. Will it work if I use an OBD I integra gsr wiring harness and an OBD I integra ls ecu?

well if you have OBD2 ignition components on your 99 B20 engine, its easiest to just keep the OBD2 electronics on the engine...so your best bet is to run a 96-01 integra LS engine harness on your car. It will be compatible minus a few plugs. Then just use an OBD1 LS ecu to power the engine. It should all work just fine if you follow these suggestions.

Yep, then all you will need to wire up is knock sensor to D3 using the P75 (LS) ECU.

I have all the OBD I components, and I definately need it to be OBD I. But I don't have a wiring harness yet and I found a good deal on a GSR OBD I harness. I'm just wondering if it will work. If so, then all I need to do is buy it and I'm complete. Plus the vtec wires will be there if I ever want to go crvtec.

Yep, leave the vtec hanging to tempt you to throw on a vtec head.

Cool, it will work. Thanks for the info. If anyone has any other comments or suggestions, feel free to add. Thanks.

err no there's KS for OBD1 LS ecu's... didja forget ?

I've already found a plug that fills in the connector to the knock sensor so it doesn't collect grime.
