How to install a wire boot or grommet in the clutch delete plate for running wires into the cab on a 4th Gen RAM truck
This isn't a complex thing to do, but I've seen a number of people lately asking where the clutch delete plate is and how to best get wires through it. Since I was doing just that I figured I'd photograph the process and do a quick write up. Because this method uses the clutch delete plate it will, of course, only work on a truck with an automatic transmission.
You will need:
- Rubber boot or grommet.
- Appropriate size hole saw or drill bit for the above.
- 15mm deep well socket
- Ratchet, universal joint and a couple of extensions.
- Utility knife
- Optional: Cordless ratchet
- Optional: Plastic trim removal tool
I used a Daystar Firewall Boot and a 1.25" Hole Saw. You can us a standard rubber grommet instead of the Daystar, but the Daystar gives you a lot more flexibility down the road for adding more wires.

This is the clutch delete plate from under the hood. It's on the driver's side just to the right of the brake booster:

And this is from the inside, looking up from the driver's side footwell.
You'll need to remove the two nuts indicated by the arrows in the picture using the 15mm socket and your choice of u-joints, extensions and ratchet. If you're using a cordless ratchet you'll want to break them loose with the hand ratchet first.
Once you have the nuts off the plate just pulls off from the outside. Due to the length of the bolts and how snugly they fit through their holes, you need to pull it straight out. Mine was trapped under the firewall material at one end (see picture below) so I used a plastic trim removal tool with a curved end to push the material away without damaging it.

Once you've got the plate out get your drill and bit set up and clamp the plate down to a solid work surface that you don't mind drilling into. I used a drill press because, well, I have one.
You want to drill your hole in the middle of the puffy area of foam. You can scrape the foam off first if you want to, but I didn't bother because the hole I was going to be drilling would be removing most of it anyway.

Once you've got the hole drilled, clean up any burs from drilling and any excess foam that would interfere with the boot/grommet with a utility knife.
Insert the boot or grommet into the hole.
Put the plate back in from the outside and secure it with the 15mm nuts from the inside.

I stuck a pen cap in the end of the boot as I knew I wasn't going to be able to get to the wiring for a bit.
