I am going to use the EGR for my wideband. I just want to make sure I connect it correctly to pcm. I did a search but I couldn't find the answer I was looking for.

Pin 55 on blue connector (egr pintle position sensor signal)is what I have seen to connect to.

Pin 48 blue connector(egr pintle position sensor 5v reference)

pin 23 blue connector(egr sensor ground)

I have a LM-2 wideband

1992 chevy truck with 2004 5.3 LM7 1999 pcm.

Do I just connect to pin 55 so I can use hptuners(not pro version) or do I also need to connect pin 23 for ground?

I will be adding my a/c request so I want to get the wiring for the wideband done at the same time while I have everything apart.

Thanks Joe

I believe its pin 55. I bought the pins/ connectors to pin in the harness from delphi they sell as a pack of 5 I believe

I just bought some pins off ebay. I thought it was pin 55 also. Thanks

It will take lots of patience it was a pain. I couldn't get the pin to slide in easily went to radio shack bought a set a really small needle nose pliers

I have done it before when I added my vss and didn't have any problems. Hopefully I didn't just jinx myself.
