I've had several versions of gas tank skids & replaced my OE '97 gas tank skid with two different aftermarket skids but I don't recall a wiring harness connector on any of them. So I'm a bit confused here. And to refresh my memory, I just looked at the 1997 Mopar factory IPB (illustrated parts breakdown) for the entire gas tank skidplate and there is no wiring harness connector shown... and it doesn't look like what is in your photo which doesn't look familiar to me
Edit: Wait a minute, I now see what you're after... I need to look in a different section of the Mopar parts listing, that part would not be on the IPB for the skid plate.
