New guy. Refreshing an '06 Border Patrol Tahoe.

I'm getting things cleaned up for the header installation. The grounds all look good! I'll grab some new O2s and HPtuners software is standing by.

This wire looks cut by the driver's side frame rail. I'm not sure if it was from service or emergency lights in it or old factory fog lights. Chasing the wire, it looks to travel up to the firewall. There are some patched wires under the center cup holders but I didn't test them for continuity just yet.

There are no fog lights installed, so there's nothing to reconnect.

The only other thing I didn't like was this. That cable has a mount there on the outside of the frame rail. I didn't like that it protrudes into the fenderwell. Road debris could do a number on it at an inopportune time.

The suspension looks good, otherise. The front axles are actually holding up, this time. I still think pulling the stiff anti-sway bars is a bit more forgiving on the rest of the chassis and suspension. It may corner unnaturally well with those big bars on it, but I think the rest of the chassis and driveline pay a certain dear price for those faster cornering speeds. This is still very forgiving on our pot-hold and rutted dirt roads.

That wire in the 1st pic almost looks like it could've been a block heater. What does the attached tag say?

It had a little electrical diagram on it for the 3 wires. No real identifier or P/N.

BTW, love your header install shenanigans. I'll be getting mine ceramic coated .

That's exactly what I was going to say, 110v AC. Tag says "operates below 0°F" or similar I'd bet.

Do they attach back by the flexplate, on the block? The wire looked to travel back there somewhere.

I bought a former CHP Tahoe years ago and fixed it up and drove it for 5 or 6 years. Mine was a 2002, 5.3L 4.10 gears. I found another Tahoe being parted out with full nice leather interior and did a full interior swap, added heated seats. For police duty it also was set up with Dual Batteries which I liked a lot. The body on mine had been hit more than a few times and even after having it repainted the damaged parts would show in certain light so I sold it. It was a great driver, had plenty of power with the 4.10 gears and my MPG was the same as I have had with newer rigs that had the 3.42 or 3.73 gears. For highway driving I prefer the 3.73 gear set but around town and for towing the 4.10 gears were hard to beat. Good luck with your project.

While your oil pan is off make sure you replace the Oring on the oil pick up tube at the oil pump. They all fail and leave you with no oil pressure. $3 part but all that labor to get to it. You will already be in there so do it.

Left rear side of the block, I think right below the exhaust manifold around cylinder 7's area. Should never be needed where you are.
