Ya pretty much but I couldve gone to the ignition switch harness but the radio harness has the VSS wire (speed sense) that the DIC needs so help calculate mileage.

I Thought I had a printout of the plug end wire colors. I can print one up at work tomorrow and upload it here to show you what and where to hook up.

THANKS!

Could I run it to the fuse box, or would that not have what I need in it? (VSS)

And what years/models was this in? (when I go traipsing through the salvage yard) Just the Denali's?

I got it out of a 2001 yukon denali. May be in other vehicles but not sure which ones.

Yes you can go there for power. But the VSS is at the trans, PCM or radio.

I appreciate you patience with a complete electro-moron.

I have this in my 02 Sierra. From what I've read the fuel range and remaining will only work on 98+ GMT400 due to fuel sender differences.

I was running really low on fuel (turned right and hit the pedal and it bogged low) and I switched over to "estimated gallons till empty" tab and it showed 33 miles till empty. Maybe I could have but I doubt it. Or its because my sender isnt quite right. Its got the buzzing effect. As I call it. The needle moves back and forth really fast like buzzing.

I could be wrong about thats what threw the mileage off. It could also be calculated for the 2001 Yukon with a 6.0 and AWD instead of a half ton 2WD with a 5.0.

Does it seem to be right on MPG's? Maybe it just doesn't know how much your tank holds. You probably have a different capacity. A Denali would have a larger fuel tank, I would think.

Obviously grille swaps and interior swaps, caddy/escalade front end swaps.

If you are painting the door handles, the older trucks had smooth handles rather than textured like the newer trucks. 88-94 I think?

Kodiak door handles swap over although rare and expensive.

Go to a junkyard and grab an extra set of corner lights and the wires. Drill a hole in your upper corners and cut and glue the junkyard 194 lights so they will both light up.

2nd battery tray from a diesel (I think 454 trucks had them too)

Gmt400s have separate low and high bulbs so why not wire them both up? 4-high mod costs about $10

The brake lights only use one bulb, but you can wire the second one to come on so you have brighter tail lights. The factory used a dual filament bulb, but never wired the top bulb to the brake light circuit....

I read that you can splice in a switch and relay into the front axle actuator circuit for a 2WD LOW, but I haven't done that yet.

Wire a switch to the ABS circuit. Just pull the fuse and plug in a piece of wire with a new fuse and switch.

S10 blazer dome light lens fits the sunglasses compartment on the over head consoles, you'll have to wire in a dome light.

You must be registered for see images attach

88gmctruck added a Vortec windshield washer tank and gmt800 nozzles to his TBI truck for extra capacity and more spray.

Thats true too. Ya it seems to be right with the MPG's.

My came with the 2nd battery tray. 5.0 2WD

Hmm I think the cargo bin thing was an option. I think the dizzles and big blocks always had dual batteries though, right?

Also iirc the NBS ad244 145 amp alternator swaps right over on vortec trucks.

I might be wrong. I'm out of town right now using my phone and not easy to look up stuff. Just going off the top of my head.

Though not oem exactly, I gained a extra .5-1 volt under load by adding a new 2 awg body-battery ground strap. Very cheap and easily to do that will improve any vehicle.

A 34/78 battery fits and is a side and top post versus a normal side post.
