my buddy is doing this swap and i have to do the wiring. the da is obd0 and the h22 is obd1. he's using the obd1 ecu. can i use a stock b18 engine harness and run wires through the firewall for the sensors the non vtec harness leaves out?

 

Thats exactly what yo do.
Shouldnt be too much of a problem.
I forgot you might have to change dizzy plugs or at least repin it.

 

it'll work

 

Yea I think the dizzy is the only plug that is different from OBD0 to OBD1, Just put a B18b OBD1 in my OBD0 Crx and everything pluygged in, I image its the same, I thnk you only need to run wires for a knock sensor and of course the vtec stuff, good luck post some pics and vdeio when is done, i like this idea maybe I'll do it to my DA

 

well if the da is obdo 90-91 then go try to but an obd1 ecu on the ecu wiring side. You need the conversion harness/4 wire o2 sensor/sub harness for vtec/knock


and if your running a p13 ecu you also need to wire in the egr valve found on all h series manifolds. This applies to f series accord motor also

 

Having a spare H22 harness around will also help too, because your going to need to lengthen quite a few of wires.
