New to Forum, and Ram's

[KevinJB]

2/17/2021 ordered a 2021 Limited 3500 4x4 Crew Cab, long bed dually, 6.7 H. O. diesel.
Delmonico Red, Night Edition, Air suspension, 50 gal, Limited 1 group, 5th wheel towing prep, Trailer Tire Pressure Monitoring system.
Now we just sit and wait for 3 months.
Came from decades of GM truck's, but with a little push from the wife, decided on RAM this time. Will be trading in 2015 GMC Denali 3500 SWD Duramax (76000mi) due to needing to get a higher payload for a newer 5th wheel toy-hauler in our future.

Sounds like you ordered a really nice truck. Congrats and welcome to the forum. It will be interesting to hear your opinion of the RAM after you’ve had it for a while. I predict you’ll like it a lot. Good luck

Finally got the truck. Installed Reese 27k 5th wheel hitch, but problems with the head and hitching up. Working with Resse on this issue. Just had PPF put on front end. Need to install my dash cam, but the fuse box is under hood, not in the cab, so I have to figure out how, and where, to get wiring through firewall.

I found that a good spot to run a wire (or bundle of wires) into the cab from under the hood is through the clutch block off plate. If you look up into the wheel well the plate is there just left of the brake pedal where a clutch would be. It's two bolts to remove it and then you can drill a hole to run wiring and the use a grommet or silicone sealant to seal around the wire.

Also, if you have the factory aux switches I've read that there is a "pass through wire" built into the truck that can send you power into the cab.

Thanks, and the pictures helped. Those are a couple hefty bolts to hold on a plastic cover. Thanks.

Haha yeah, I think they are the same size as if it were to actually be holding on a clutch master cylinder. I went this route since if I ever want to reverse it (or if I messed it up!) I could just order a new clutch block off plate and if would take 10 min to swap. I assume not an expensive part either, although I didn't look into it that deep. Also nice to be able to do most of the work while it's off the truck.

The 19-20 trucks have a single pass through circuit that terminates on the upfitter plug under the hood and the grey jumper in the cab.

The 21 has 3 additional pass through circuits that terminate at blunt cut wires near the PDC under the hood and at the other (black/white) upfitter jumper in the cab.

AUX pass-thru wiring.

Let me start by saying I am truly sorry for once again bringing this up. After I plug this harness in to the gray connector under dash the single wire is my pass thru #6? And than that loose wire can be hooked up directly to a device with in side the cab ? What do you all do with the extra...
