My harness for my EM1 is trashed but I have a 2000 GSR parts car. Will the engine harness and the subharness that pulls through the firewall work in my EM1? I would also rather have the 2 piece harness like the teg has. I hate having to take my battery out and pull the whole thing through the firewall everytime I pull my motor.

 

you'll need to swap the intire engine harness back to the ecu...your em1 harness is a 1 piece harness the integra harness is a 2 piece harness like on the 92-95 civic egs...you can use a harness from a ex civic 96-00 or swap the hole integra harness I THINK, NOT 100% SURE ON THAT...I used my ex harness when I swapped my gsr motor

 

Flat out does not work.

Unless of course you want to extend a bunch or wire and change plugs on various things that is.

There are too many differences between the two types of harness set-ups to be even remotely plug and play.
