Help me figure out what this wire is to.

[Zebvance]

So I ended up ripping my block heater wire out wheeling. I was looking for where it plugs into the block to make a assessment of the damage and couldn't find where the connection it. But while I was under the jeep I found this. Looks just like a grounding wire because it has no insulation on it. But where is it suppose to go. Also looks like it is coming out of the wireing for the plug above it. Which I am guessing is the oil pressure sensor??? Some help would be great guys. Thanks in advance.

 

 

 

In this picture you can see it to the right hanging out of that harness.

The oil pressure sender is on the passenger side, next to the oil filter.

 

I think what you're looking at is the knock sensor. I have no idea what the bare wire is, though.

The truck runs fine. Beside having a very strong exhaust smell all the time and I get crap gas millage. Just happened to look of symptoms of a bad knock sensor and found this. Not saying that it is bad, but to me it looks like a ground ground wire without insulation. So if it's not grounded properly it may not be functioning right.

 

 

 

Idk all this is just a though.

For got to mention its is a 88 renix 4.0 auto. I have 4.10s with worn down 32s and a 4.5 inch lift. I get about 13-14 highway and 10 in the city. Motor has 107k on it.

This guy describes a braded wire also.

Ground wires within a harness most always are insulated. To me it looks like a strain relief wire for the harness due to the heavy gauge of the wire strands.

Have your speedometer and odometer been recalibrated to adjust for the larger tires and non-stock gearing?

No because it is in kph. This is a Canadian model. I keep

I didn't say anything about miles or kilometers. If your odometer hasn't been recalibrated, you can't calculate your fuel economy because the distance your odometer says you drove since the last fill-up probably isn't correct.

Yea I get that. That's why I said I track speed and Mileage by gps...

My block heater is on the driver's side of the block, if memory serves, it was a little forwards of the middle of the block, but my memory is foggy. It's replacing a freeze plug, and will have three prongs sticking out of it. Given that you're in Texas, it's probably safe to say you don't need the block heater. I'd just leave the cord unplugged. I always pull mine off for the summer; it keeps the engine bay a bit tidier.

Also, I can't see your pics...

Knock sensor connector looks identical to a fuel injector connector. Won't affect squat as far as driveability.
