Hi, I bought a 94 toyota 4x4 22re and the wiring for the O2 sensor had been hacked up by the P.O. I bought a "universal" O2 sensor and am having trouble finding/understanding the a wiring diagrams I found. The univerals O2 sensor has 4 wires 1 blue, 1 white and 2 black. Any ideas on how to wire this up to my truck? My truck has 1 black, 1 brown, 1 white/red, 1 black/yellow. I think... that is going from memory..
