Hey everyone. As previously stated I have an 88 EF Hatch. The main harness and engine harness are still obd0. I plan on putting a P28 with hondata in. Should, or can I convert the whole harness to obd1? This way shock towers are done and then I can run the injector wires straight to the shock tower? If this is possible is it difficult. Thoughts? Opinions? Success failure. Thanks.

 

I'm not following the question. A harness is just a bunch of wires with plugs. If you want to build your own harness, you just need to source the connectors and appropriate wire. Alternatively there are OBD1 harness's available for an EF. I run an injector sub harness and OBD0 to OBD1 jumpers. It isn't as clean but have never had anyone mention it in 20 years.
