RacerJJ Posted September 27, 2007 Report Share Posted September 27, 2007 I bought some new Denso sensors but they have the wrong plugs on them. I plan to just cut them and splice the old plug onto them. Just looking for a little feedback and info on this. Are all of the wires the same (just wire) or do I need to make sure they match up in the correct sequence? TIA... Quote Link to comment Share on other sites More sharing options...
chpspecial Posted September 27, 2007 Report Share Posted September 27, 2007 You have to make sure that you wire them correclty, and match the colors. you don't want to mix up the signal and grounds, that would cause havoc on your PCM Quote Link to comment Share on other sites More sharing options...

RacerJJ Posted September 27, 2007 Author Report Share Posted September 27, 2007 BUT....... sometimes the coloring is different for the same wire Yes, you are correct! They are different but, try to follow me here...on the new sensor there are 2 black wires on one side and a blue and white wire on the other side. The plug that I cut off of my after cat o2's (these may have different wires from the fronts, I don't know yet) have 2 browns on one side and a purple and a tan on the other. Is it safe to assume that the 2 blacks on the new ones are the same as the 2 browns on the old ones? Quote Link to comment Share on other sites More sharing options...

Yes the front and rear are different. yes the black and brown wires are the same, in MOST cases they are ground. Quote Link to comment Share on other sites More sharing options...
12'SROCK Posted September 27, 2007 Report Share Posted September 27, 2007 (edited) OK found this that will help you out connect the following wires: denso o2 gm wires black--------------> brown = OE heater black--------------> brown = OE heater blue---------------> purple = OE signal white--------------> tan = OE ground Edited September 27, 2007 by 12'SROCK (see edit history) Quote Link to comment Share on other sites More sharing options...
