What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[Scott in AZ]

No, but I'm about to run some switch wiring. Is it hard to unwrap the tape and fish it through with all the other wires? That's what I was planning to do.. fingers crossed..

Mike Z71, please take some pics. Happy hunting, bro'.

Was scoping out the wiring for a new subwoofer amplifier install in the front center console, under the cup holder. Going to run power in thru the main grommet, i guess… but I hate the thought of taking an exacto-knife blade to the grommet. I think I’ve decided that’s the best way to go.

While was under there I fished a golf tee out from under the front seat inboard rail from the Silver Lakes Robert Trent Jones Trail course in Anniston, Alabama …. That means that tee has been there for 20 years!

Did you guys power your amps thru the main grommet or drill a new hole in the firewall?

Poke or drill a hole smaller than the wire and push the wire through. The rubber will stretch but keep a firm seal around the wire.

I ran a power wire last weekend to under the second row passenger seat, through the floorboard. Used a neoprene grommet with an ID just a little smaller than the wire's OD. The wire's outer jacket is neoprene, so they're both the same soft and flexible material. I had to use a squirt of B'Laster ever so often to help it slide through the grommet. The fit was so snug that it wiped the lubricant off after a few feet:

Grommet was like this:

I drilled the hole, painted the metal and let it fully dry to prevent rust. Popped in the grommet then fed the wire through:

If it's more like a winter thing, I'd be down to sword fight with you fellas disney meet up?

I ran mine across the firewall from the battery junction block across the top harness over the brake booster down the driver's side frame harness and up through the grommet in center of the driver's floor for the parking brake cable and under the carpeting/door sill plates/interior trim to the desired location.

Hey Wes, when you are making those high speed runs, does the transmission run in the over drive gears at WOT or does it hold in 4th?

 

[Charlie207]

Changed out my chrome accented power mirrors with all black ones. Part of my Chrome to black change on the vehicle, plus the passenger power mirror motor failed.

I'm doing the same thing! Just received one of the Dorman covers from Scamazon, but the other side is going to take several days longer. They will be the shiniest things on my truck.

You are doing covers only?
I'm glad I found a set at a yard. Replacements with motors are very expensive.

Yeah, if you click that green link in my signature you'll see that I only need to get rid of the chrome grossness on top of my side mirrors.

I hear ya. I really didn't like the fake chrome stuff either.
About the only thing left for me are the door guards / trim with that shiny plastic junk. Not sure what to do with those.

with the blackbear tune it holds in 3rd up to 100mph/5800k (rpm is guess it gets close to 6), then it kicks into 4th
IF I keep @wot with my foot in it, if I let up at all it bypasses and shifts up.

Will do, should happen within a week.

side mirror caps, you can buy flat black ones from gm for about $35 a piece. The painted covers look odd to me as well, dunno why. I havent put mine on because im hoping for mirrors without the damn arrow..

shift schedules, stock wont shift into 5th until 126mph(87% and up throttle) or 131mph(WOT). should hit 100mph in 4th if you stay above 60% throttle.. unless your limiter kicks in..
Oops need to add, that is 3.08 gearing

So you can cruise at say 115 in 6th?

hmm, not sure to be honest I will have to test and see, I was cruising last night at a little over 100 maybe 105/110 but wasn't really paying attention to what gear I was in. usually not able to maintain a high speed like that for long because mexico is not that big

That's the same problem @iamdub has running around Cuba.

Since they took my boy Pablo out 30 years ago, keeping my mules in line requires extensive measures.

Installed the alcohol content sensor.

Location! The freaking acoustics literally muted the bass. The sub was between the second row captain's seats. Originally firing upward but we tried all positions (giggity). The sub was working hard. It was making sound the whole time but the bass frequencies were being absorbed by the...

I don't know why it wouldn't do that aside from the extra load from wind drag.
But technically speaking, if you adjusted shift points you could make it happy to be in sixth at those speeds and loads.

I can tell you at 115 she's thirsty, doesn't matter if you are in 6th or not

Mine gets twice the MPGs from 100+ as it does from 70-99.

Mine gets twice the MPGs from 100+ as it does from 70-99.

Once you push past the sound barrier, drag is sharply reduced.
