91 crx si had first gen JDM b16-- I wanna put a b18c1 into it...

Question-- Will all the plugs on the b16 engine wire harness fit my GSR sensors
(I am assuming that because I'm using the GSR ecu, I will want to maintain GSR sensors)??? If all the sensors do not fit, what type of wiring am I looking at to satisfy my ECU.. Also I'm guessing there might be some sensors for OBD1 that aren't on OBD0 wire harnesses or visa versa??? If so, what are they? I figure I will simply be running those wires directly through the firewall to the ecu plug myself--- please correct me if I'm wrong guys and help me out with the fuzzy details if you could also.... Thanks a lot.

---- Details incase it matters-------
Car as I got it--- 91 CRX Si w/ first generation JDM b16 (DOHC Vtec).

Doner car/engine specs: 94 GSR b18c1 (OBD1) with JRSC- RC440 injectors, hondata chipped gsr ecu.

Intentions for the Hybrid--- pull JDM b16 and swap in b18c1... and use B18c1 ECU!

I know I have to get the obd0-obd1 conversion harness for the ECU... I ordered one a few days ago from Boomslang....

The only sensor I can think of that will not be the same is the coolant temp. It's on the back of the block of the B16A as a big rubber plug with 2 female connectors. On the B18C1 the coolant temp is on the thermostat housing as a regular round 2 prong connector.
Since you will be changing to OBD1, you will need to eliminate the injector resistor box and change the injector slips to OBD1 if the 440's are OBD1 which I imagine they are. The distributor plugs will need changed to OBD1 and you will need to wire up a 4 wire O2 and the IAB for the GSR manifold. You might have to extend a few wires, but overall it's not that bad.
