Angry Monaco Diplomat 99 Wiring

Hi all!

This is my first post ever here, so apologies if I make any mistakes!

We have invested in a 1999 Monaco Diplomat and have been doing it up and learning lots along the way. We’re anxious for our first road trip, but have hit a snag:

My helpful (??) teenage son noticed the drivers side electrical panel (on the left of the driver, not the dash in front) was broken and took it out to see if we could 3D print a new one. Unfortunately, when he disconnected all the switches to remove the plastic surround, he neglected to record which wires/socket went to which switch. So I have a selection of switches and sockets/wires and trying to piece it back together.

The switches are:
- Step Cover
- Cruise control
- Exhaust Brake
- 2 unknowns (they do not have covers on them saying what they do, but they do work as switches)

The stabilizers / gear selection are on the same panel but they’re all fine.

Does anyone have a photo of a working side panel so I can identify the 2 missing switches? Or even more amazing a wiring diagram? There are only 3 sockets, the rest are loose wires. I’ve worked out the orange and white wires are to power the lights in the switches, but this leaves me with 2 bundles, one with one black and 2 red wires, and one with 2 individual wires.

Any help would be greatly appreciated!

I have a 2000 Dynasty- so maybe mine is close enough.

I looked through my photos, and I have part of you need. It will be a couple of weeks until I am back at the rig. Then I can take all the pictures you could want. I also have the 2000 wiring book.

The only switch I can remember that is not on your list or my photo is the battery tie solenoid. But there are two switches not really in my photo.

Good luck - hope it helps.

Welcome to the forum: As you now know, always take pictures before any changes. Never rely on your memory.

Take a very close look at the wires, with a magnifying glass and a headlight if you have one. There may be some writing on them to help you.

Now is a good time to post some pictures of the wires. The number of wires on the switches can be telling. And by the process of elimination some of the plugs may not fit certain switches.

The previous post may have your issue resolved but wanted to welcome you to a great forum.

Ok, you guys seriously rock. Thank you for all your help, I cannot tell you how appreciated it is.

My RV is in the shop just getting checked out mechanically, but I'll be back on trying to fix the wiring this weekend. The electrical diagram l1v3fr33ord1 posted is gold and exactly what I was hoping for, but all the responses were greatly appreciated.

I'll update the thread with how it goes, what I discover and photos.

Thanks again!
