I followed the truck to the shop. That was the fastest it moved in years.

Electrical / Re: TCC lockup pin location

cool thanks for the feedback.  The X vs X max are much different however: the X Max will do Drive By Wire and Automatic trans control

I have yet to prove my theory but from my poking around it seems as though the drivers are in both boxes. I haven't verified the pins but the x has plenty that aren't used.The major one that the x absolutely might not have is likely drivers for DBW. I'm currently using a 4l60e config for my 700 so I can use the VSS signal for special functions. Maybe one day I'll test this out by pulling a config from the global and seeing if the pins work. Wouldn't be the first time a manufacturer made something exactly the same but marketed different.

General Discussion / Re: Something quite polarizing... Train horns

« Last post by frotosride on August 11, 2026, 10:59:34 pm »

I've had a triple horn manifold and one separate horn with a 13 gallon tank for years and to this day my body still cringes Everytime I touch that switch!! Absolutely my favorite thing I've ever put on any vehicle!!
Years ago when I first got the triple manifold, I stripped them down, cleaned all the casting flash and polished the internals, drilled out every fitting so I had a true 3/8" hole everywhere. I have about $12 in my system but never found a compressor I wanted to afford.
Thinking about an ac compressor setup when I get it back on the road again.

I always wondered about using one of those old 60's ford york compressors for this.  they used to be cheap, probably big bucks now.

Yes they are, there are complete kits now but I'm not paying for that. My plan is to drill and tap the oil passage in the perforator plate and hop that the pistons don't have to have oil on top, and the circulating oil is as designed for system components. Thinking about trying it on my Duramax first.. if it last ther it'll definitely last on an LQ4.

Okay now the embarassing post.

So I drive the truck to work, air horns primed, get home, park in the garage, close the door, I'm getting out and my lunchbox hits the horn button...      God it was so loud and unexpected!  If I woulda had to pee I would have. 

Been there! That's why I removed my ash tray and made a bezel for the horn and rear locker buttons.

yep JP. plans are to install stereo equipment. But, as you said, a left/right exhaust song is good listening too! The H-pipe kit is a Summit item.

Nice truck BTW.

I bought my '78 K10 step side to flip. 10 years ago! 

I would clean it good, even use 1000 or 1500 grit (with running water) to knock down the visible crud.

Then clear coat it with a satin or flat clear.

That would seal out the water, and ensuing rust.

Can't speak to the undercarriage.

Clever!

So it's electric? I thought that year range was still a mechanical cable.

I like the idea of a 'gentlemen' flowmaster. I think as we get older, the brash sound of a loud muffler is more annoying.

Having said that, there ARE moments when you feel like letting her rip! Do they make a crossover?

Asking for a friend...

13 years ago almost lost her, in the Adairsville, GA 2013 tornado but as bad as that tornado was and all the destruction it caused, my truck came out without one scratch on it.

That tornado destroyed so much in the entire area but somehow I made it out.  When we finally got to go home I had to drive through 3 foot deep water 4 times to make it.  flooding everywhere, big mess.  God was on my side that day.

I was working for a guy flipping houses.  This is before I got the van and spent 2 years or so working out of the truck.  WOOOO!

The porch rail i put up was all I got done.  The tornado came up quick, we ran to that lil closet in the center of the house.  when I came out all my tools on the porch were gone including my nice skilsaw, but on the window sill my lil torpedo level was sitting right there.  crazy as heck!

Me and Mr Brown Took all our food and water out of our vehicles and hid in that house in a tiny closet.  We made it.  I had my makita radio with us.  We were fine until the AM band went out then we got real scared.  If AM goes out you're in big big trouble.

When we came back out gas lines had been broken by those huge tree roots.  couldn't smoke, wouldn't dare try to start a car because of fear of the sparks the starter might make.
