Time to install a new Painless Wiring harness and make a DIY digital dashboard. Also, I get to go on my first test drive with the new LS Motor!
In Part 7 we left off having installed the throttle cable, Intake, and ECM computer mount.
Installation of the Painless Performance Wiring harness is relatively straightforward but takes A LOT of time.
First you widen the hole in the firewall like the directions say then start loosely routing the wires.
Woof, that is a lot of wires…
My plan with this project is to upgrade and modernize where possible, so all of the lights are getting upgraded to LED’s and the dashboard will be all digital.
I picked up these little gems for CHEAP on Amazon. Check them out on the links below.
5 NEW 3/4″ AMBER LED CLEARANCE MARKER BULLET LIGHTS
10 NEW 3/4″ RED LED CLEARANCE MARKER BULLET LIGHTS
Picked up some white LED bullet lights for the rear backup lights too.

Red LED Bullet lights for the 3rd brake light.
The Painless Wiring harness has a wire for a 3rd brake light even though these trucks didn’t come with one from the factory. Nice feature.
There are a couple of connectors that are no longer made that you have to cut remove from the old harness. One of which includes the half moon connector that goes up the steering column. A really teeny flathead screwdriver inserted down both sides releases the pins one by one.
I found that it is easier to “group” the wires and route them in bunches by the area of the truck they will end up in.
More wires….
Close-up. I loosely routed the wires at first until I could make sure that everything worked. It would suck to route, zip tie, and wire loom them then rip it all apart because something didn’t work.
Also wired in some cheapo LED Fog Lights I also got off amazon. They seem pretty cool so far, especially for the price.

Here is a little trick that I learned when trying to install O rings. Grab the o-ring and hold it over your household toaster for about a minute so it is softer and easier to install.
This is where I made the junction for the rear lights. I didn’t use a quick disconnect. I figure if I have to take the bed off, I can figure it out at a later date.
Might as well go all out while I am doing it, so I wired in a backup camera.
Made a quick and dirty little bracket to mount the LED license plate light to.

Set it up so I can see the trailer hitch while backing.
LED’s all hooked up and working!
First step of the DIY dashboard. Lay out everything to get a visual. In this picture I had already traced around the gauge bezel and cut it out of a thin piece of steel with tin snips.
Drilled the holes for the switches and gauges. The holes are ‘mostly’ accurate. If anybody knows how to find the center of a circle more accurately, I’m all ears!!
To mount the Ultra-Gauge, I disassembled the windshield mount and super glued a 1/4″ bolt into the bottom of it.
Dash roughly laid out. I also mounted the GPS with a 1/4″ bolt through the suction cup mount.
Painted the steel a shiny nickel for a little bling…
Then glued the whole thing into the bezel.
Mounted the switches and routed the wires. I used the back of the Ultra gauge bolt as a common ground.
Removed the back cover from the old gauges to use as a base for routing the new wires.
Gauge cluster all wired up. I had to re-use the Tom-Tom plug because it had a transformer in it that put out 5V…
Close up of the completed Ultra-Gauge mount.

View of the mostly finished dashboard. I totally forgot about the backup camera until after the fact, I ended up zip tie-ing it to the steering column.
It’ll work…
Wired up the gas tank. It didn’t fit under the truck like I had planned. So this is plan B until I find an alternative.
It’s alive!!!!!!!!!!!!!!
Fires right up the first time… every time. I LOVE fuel injection.
Took’er for some hot laps around the neighborhood. So far everything works great. The brakes even work better now since this engine has more vacuum.
After about 3 months, I finally got to drive big bertha out of the garage. I definitely don’t regret the swap. I feel the reliability and increased gas mileage of this LS engine will totally be worth it.
Stay tuned for some more pictures as I clean and finish up the details. Maybe we will even get some video of the beast in action!
