WideBand Volvo/Bosch

Post by FubarI33t »

I got a wideband from a 90's Volvo SOHC Turbo. Unfortanetly I do not remember the model. Problem is, it has two solid white wires, and one black/ground wire. I do not know what white wire to go to a ign hot, and that wire to go to MSII V3.57. It is a Bosch O2, even has the same 2 plug connector as there injectors.

If it only has three wires, it's not a wideband. Chances are the two same-colored wires are the heater power and ground, and the third is a narrowband signal.
