What did you do to your NBS GMT800 Tahoe/Yukon Today?

[ivin74]

I'm going with the 2020 setup. I got the rotors & calipers off a wrecked 2020 Silverado.

What you end up paying for them?

Almost half way. I'm in no hurry and work slow and deliberate.

I work slow also. You didn't wanna chop a hole in the floorboard for easy access?

$150 for the rotors and calipers. Truck had 44k miles on it when it went boom. The pads still had 50% life or so but I just got some new PowerStop z36 pads.

The first time I dropped the gas tank (replace fuel pump) was a little bit of an adventure that I crawled through slowly.

But the second time I dropped it (to run new brake lines) the whole thing took 15 minutes, and most of that was using a little transfer pump to move gas into a can.

Whos up to date with what EFan harness to buy? Pretty sure the PO that wired mine screwed something up and its causing the driver-side fan relay to burn up. IIRC the Nelson performance harness has been known to have issues, anyone know if an OEM one is available?

Hit up @ScottyBoy- he sells used OEM ones that he’s cleaned up and re-loomed plus he can instruct you on how to install it. I tried a couple aftermarket ones and even beefed one up and it still melted. No problems since going to the OEM harness and relays.

Edit: it looks like you have the OEM relays which are part of the OEM harness so I’m not sure what’s up. Have you looked at the thread in the tech section that shows how to wire that harness? Iirc all there is to connect is power, ground, the green trigger wire that goes to the pcm, and the 2 plugs on the fans. There isn’t much to screw up. Maybe you have a fan going bad? Try switching the fan plugs so that relay runs the other fan and see if the other relay melts.

Thank you for the response I specifically remembered you having an issue with them at some point and figured youd know the ultimate solution!


All the wiring is the same color and red so its a PITA to trace but I will if it gets down to that, I switch fans with a different set of fans so I'll see how long that lasts. Seems to last about two weeks before popping but I'm not driving it this week so it will take awhile to know if this fixed it. I'd also love the OEM fusebox cover that has the second cover for the fan relays, its a pita to pull the entire box everytime.

Is there a change your entire truck can go up in flames... looking at how much that area melted??

I may be carried away, but I'd disconnect the battery when it's bed time?
Or pull the fuse?

second time around is always faster, you know how to get that job done already. hardly have to think about it really lol

First time is a learning experience and takes longer. And the second time around everything's been apart already, and most of what's going to break has broken.
