99 civic ex

picked up a 99 ex. it has a b16 block with a gsr head… the whole car needs re wired because its all fucked up. anyway, what wiring harness and ecu do you guys suggest i get?

Gee, how about a 99-00 civic si.

thats what i was going to use but i didnt know if that would work on the gsr manifold

i’d get an obd1 gsr harness and make it obd1, unless you need emissions, then go obd2a gsr … really, you can do whatever combination you want.
