Hey HT im just starting to put together my h2b swap now and i decided to make sure my wiring harness was all there so i hooked it all up to the engine but i dont have the part that goes from the engine wiring harness to the ecu. its a 1997 prelude and im pretty sure its pm5. and ideas on what that piece is called or where i could find one?
Thanks

 

you mean an obd2 to obd1 conversion subharness ?

 

Sounds to me like you need the whole harness that goes through the firewall. I would start by scouring junkyards, or find someone parting a complete car.

 

Yeah I think I need thue harness that goes through the firewall. I'll post pics if what I have

Found the issue, Prelude engine harness is not compatible with the civic setup, need to splice together the harness from the d16 with the h22 harness

thanks for the help
