I'm currently installing an ARB compressor and lockers in my 98 K2500 and really wanted everything to look as factory as possible. I figured I'd share how I put together a custom harness and switch combo. The top position of the triple switch retainer needs a little trimming with a Dremel to fit...
I'm struggling to locate the color code or name of the dark grey accent color that surrounds that the gauges, HVAC, radio, etc. on ALL 95+ GMT400 dashes. I'd like to customize some switches to the right of the gauge cluster and paint them to match. Just to be clear, I'm referring to the the dark...
I’m trying to delete the PCM on my 1998 K2500 Cummins swap and rewire my factory fuel gauge.
Truck was originally a gasser with a single fuel tank.
Pin 13 on PCM connector C3 (grey/clear) is “Fuel Level Module” coming in from the in-tank sender and pin 9 on PCM connector C1 (blue) is “Fuel...
Just to be clear. My original post was more of a question of curiosity than of concern for needing to fix the brake system.
I’ve put 2000 miles on the system at this point and the truck stops great in all conditions. My ABS module could very likely have been malfunctioning, but this is...
Are you suggesting that the 3/16 braided line to the 1/4 rear hardline is what is causing the rears to lock up? Seems like that would be restrict flow and if anything, weaken brake pressure to the rear.
I’m positive the radii on the braided line bends are fine. That’s just perspective from the...
Thanks man. My truck was originally a 5.7 auto but that pic is from the middle of my Cummins/NV4500/NP205 swap. All the details about that can be seen here:

I don’t remember the part number off hand but it was just a basic black Wilwood proportioning valve. I also used a Wilwood 10lb residual valve on the line to the rear axle.
Flairing stainless hardline for first time ever with the OTC flair kit I bought was a complete failure... Every line leaked. There is definitely a learning curve to it.
The loops are engineered for a reason but it’s not for cooling. It is to accommodate the body of the truck flexing independently from the chassis.
I went with braided lines after failing to properly flair stainless hard lines...
This is a K2500 and the bolts contact the main axle shaft flanges, not the CV shafts. I trimmed one edge (about a 1/4”) off the bolts for them to slide out. They could be installed “backwards” and still clear everything but since the new “slim head” design fits easily I’m gonna reuse them in the...
Jesus Christ... My Cummins swap doesn’t leave enough clearance above the front diff to push the axle up out of the way. Removing the front axle for this seems like an outrageous servicing requirement. Now I’m thinking about just reusing my new 5 sided bolts...
I've asked two mechanical engineers in the automotive R&D field about installing the new bolts "backwards" and neither could foresee any issues with bolt or bushing integrity with this particular application.
I'm trying to wrap my head around why they would be installed that way from the...
