Delco AFS-74 heated O2
Just got my Delco AFS-74 heated O2 sensor, brand new in the Delco bag.
I have searched on here, and usually the color wires are 2 black, 1 white.
this new one has 1 purple and 2 brown
Am i to assume, that the purple is to go to the computer and the 2 browns are 1 power and 1 ground?
just checking because i have not seen anyone comment about these colors before
