Default obdI 94 GSR motor into obdII 96 LS chassis

Ive searched and didnt really find the answer im looking for. A friend of mine is going to be installing an 94 OBD1 GSR motor in his 96 OBD2 LS chassis. The GSR motor has the engine harness, dizzy, ecu, injectors. etc complete swap. i know i will be needing a ecu conversion harness from obdII --> OBDI. but what im wondering is what else will be needed, if any, to make this OBDI motor work in his OBD2 chassis. will i use the obdI harness or obdII harness? which dizzy, etc. Let me know what you guys think.

You'll need your conversion harness and you will also need to run a few wires for VTEC and knock sensor to the GSR ECU, assuming you re-use the OBDII harness.

Someone please correct me if I'm wrong but if you use the GSR injectors (low impedance) with the OBD2 main harness, you'll need a resistor box as well.
