Disconnected Wiring Pin... What for?

DENALIHD66 · April 15, 2020

I was under my truck today and noticed a wiring pin branched out from another harness. It is on the driver's side on the crossmember plate behind the transfer case. It has a plastic placeholder for it, but I can't figure out what this would be for?

Maybe for an exhaust brake harness for a diesel? What are the specs on your truck?

Is that the one for E85, if your truck is compatible?

I appreciate my response isn’t much of an answer but I can say this; I had an electrical issue with my 2016 Silverado in the winter and spent about 15 minutes under it talking to the mechanic while it was on the hoist. I have the exact same connector and asked him about it. Sadly I don’t recall the answer but I can say I didn’t commit it to memory because it was a non-event. Nothing is missing or disconnected, it’s just for something that wasn’t relevant to my model so I didn’t care. So as I say, not an answer but also nothing to fret over.

I can positively identify this as the E85 sensor harness. Your truck is compatible if you add the sensor and adjust the tune a little bit. I just did the conversion a couple of days ago. See CJtunes.com for more info.
