pm7 ecu is the one you want since its for that engine but is harder to find...alternative is to use a pg7 if you cant get a pm7...all the info you need about the zc dohc is in the link below

if it is OBD0 DOHC ZC, it is real easy - bolts right in - use your A6 engine harness on the ZC - you will need the upper radiator hose for the 88-89 Integra (use the lower radiator hose that you have) - you will need to make a minor wiring change at the distributor - this is what you need to do for the wiring: http://www.zcspeed.com/SiZCwiring.pdf
