Looks like a motion sensor from a previous after-market alarm system.

 

This is a real question... I never noticed these before, but saw them in the side of my frame today. What are they? I don't think they are tailgates...




I posted the picture "upside down" because that's the way they were positioned in the frame.

 

Weird, never seen them on my frame. Where were they?

 

Me thinky I've seen them on mine too. No clue what they are.

 

Ive got them on my 92.. No idea what they are for.. Mine are blue though I think.. I will have to snap a picture tomorrow...

 

Where are they located? I'll look for them on mine tomorrow.

 

Front frame rail inside behind the tire on mine I thinks

 

But which side? lol

 

wow.. we really need to spoon feed ya huh... LET ME GO CHECK FOR YA!!! lmao

 

I don't feel like getting another shirt dirty to climb under my truck to look for something I can't find!
