just pick one up from my friend's wrecked evo. he didn't have the instructions. how do i hook it up to my car. i have a 88 hf with zc engine and si ecu. what wires do i have to splice or depin or connect from the ecu to the wideband. the innovate site shoe how to do it for 0bd 1 and 2 hondas only.

 

My car is "OBD1-nafied" but just have narrow-band out going to O2 sensor wire, system ground to the thermostat housing, and heater ground to the body. For the switched 12v source I just had it hooked up to one of the underdash fuses with the "add a circuit" thingy's.
