I have a harness for sale. I bought an engine that was originally a flex fuel engine that had the intake changed to a non flex fuel one.This is a flex fuel harness 2 O2 sensors are included with the harness. I was told this came off a 2004/5 silverado. First to post I'll take it in this thread gets it. I am not sure if these are the before or after cat O2s.

I will take $125 for the harness shipped

Do you know if it is for a 4l80e or 4l60e?

I believe a 4L60 but you can make it work for either. A 4L80 has an additional speed sensor that can be added. And there are a couple of pins that would need to be changed on the 20 pin round connector. If you are having someone rework the harness for a swap most will know how to do this. If you are doing a harness yourself there is information in my link below.

It can be made to work either way but I do believe it was a 4L60.
