You’re very right, however, the Mrs said I need to put love into the Tahoe and start driving it again because she refuses to do a 3 hour trip in the ranger again lol.

Glad to see you didn’t die yet either!

I haven’t done a thing to it like I said I would, but the G80 did try to kill me today. Instead of not locking like it normally would, it locked, then unlocked unexpectedly in the middle of some hard cornering. Wouldn’t have guessed it would do much however it really unsettled the chassis and strangely felt like really bad understeer. Unless the under steer was just me being surprised in the moment. Either way this thing really needs the 4.10s, truetrac, and new tires.

Anyone have a 9.5sf truetrac for sale?

Spent 3 hours shampooing this turd today. Not new looking but atleast it smells nice. I’ve had great momentum working on my new to me gmc a few hours in the morning and an hour or so in the evening when it’s still fairly cool so I think I’m gonna transition that time to the Tahoe. All this will be stuff I can do at my house with no garage and no concrete to park on.

To start was some cleaning because I have never really cleaned the interior of this truck other than shop vac and interior wipes. I doubt it was dirty Mike and the boys, but it sure looked like the PO hosted soup kitchens in this thing.

Next is gonna be what failed me today which is Efan wiring. It’s been failing for a few years now and I figured eventually the truck would burn to the ground and I’d be free of this affliction. Anyway the wiring is melted hella bad and causing the ECT to read wrong intermittently causing some horrendous bucking as the truck sees 200* to -39* rapidly while doing 60mph. Honestly was sure I’d make it home today. So I’m pulling the harness in the morning and planning to steal the one off my RCSB which is still half parted out.

Got the factory style efan harness the PO installed out of the Tahoe, man it’s roached. No idea what caused the issue other than it appeared to have melted at some splices, not sure if I did those or he did. I know the first bit of efan trouble I had was relays burning up. So tbh no idea if even replacing the wiring will fix this

Well, duh

That harness was ******. This will probably fix all of the issues you were having

Hopefully, I’ll be pretty mad if it doesn’t. I’ve had so many small electrical gremlins with this thing over the years. Makes me want to buy a carb on it and delete all electronics

Bit of a mopho pulling the Efan harness out of the harness on my RCSB. Looks in great condition tho and I made it a little over with some wrap and tape. I’m thinking that possibly the issues I had all came because of where the PO grounded the harness he installed.

The one I removed off the Tahoe had a crappy ground placed on the driver side of the accessory bracket where the positive junction thing is mounted.

The one on my RCSB which is an 05 so factory fans was grounded way over in the pass side down by the front body mount.

I wonder if being grounded at the engine instead of frame is an issue. I’ll try to install it in a similar place when I get home today.

Ok ban me if you don’t want this here, but I’ve missed all you butt lickers and this involves a Tahoe for some bit of it. Anyway this is my new to me and free 1996 GMC2500 4x4, 5.7, 4l80e, ECSB. My uncle wrecked it into a palm tree in his driveway 5 years ago and just recently kicked the bucket...

Installed the harness, all seems good for the 5mins I let it idle. Both fans kicked right on with AC on blast and no engine lights.

Another thing I think I need to replace is the turn signal doodad. When I hit the turn signal right it flashes the brights on. They easy to do?
