Wideband wiring into oem harness
I am installing a ngk powerdex in my 95' running a mspnp. The powerdex only requires 3 connections: power, ground, and signal to ecu. The stock 4 wire plug has signal, ground, and 2 +12v heater wires. If anyone is wondering why I would like to wire it this way its because I can centralize and simplify the wideband harness to a single connection rather than a one wire going over there and another over there. I don't know if its cool to use the switched +12v leads this way and if the ground is suitable. It would be nice to do it this way but will it work?
