crx-

New to posting, just wondering if you guys could help. I have an 89 crx shell with a b18b1 motor trans axles everything to do the swap except for the harness could anyway tell me which harness i can use, i found one out of a DA integra in a local scrapyard that hasnt been hacked or anything. I can get this thing on the road this weekend if i can get a engine harness. I have everything from the dash back i assume that it is obd0? So a DA harness probably wouldnt work help me out lol

Not sure what model you have but unless its an SI or HF you're going to have to convert to MPFI before you can put the engine in and have it plug in correct. After that you're going to have do one of two ways:

Method One Convert to OBD1:
-use an OBD1 P75 ECU with OBD0-1 adapter (don't use the OBD2 P75 as it'll take way too much to get it without codes)
-use an OBD0-2 distributor adapter
-if your car is Si reuse the injectors, if not you'll have to use the OBD2 injector plugs and solder them on or use adapters
-use an alternator adapter or try to find an OBD0/OBD1 b series alternator
-rewire the fan switch from the back of the block to the thermostat housing
-you can't use the transmission without a cable to hydro adapter or find a b series cable transmission
-you'll need a mount kit, can't use the ones that come with it
-you'll need to custom make the shift linkage to get it to work


If you stay OBD0 (same thing with DPFI to MPFI applies):
-get an OBD0 PR4 ECU
-use an OBD0 B18A distributor (can't use the OBD2 distributor)
-if you have an SI reuse the injectors on your engine
-OBD0/1 b series alternator or OBD0-2 adapter
-rewire the fan switch from the back of the block to the thermostat housing
-the rest should plug and play
Same as above with trans, shift linkage, and mounts
