Where do I find a layout for wiring and plumbing

[PARAPTOR]

I have read many posts asking how do I obtain a wiring diagram or plumbing layout for my rig. Thinking to myself this sounds like a reasonable request.

Well, just finishing up on a recent mod which required me to open the inners of my Raptor. Quite entertaining :eek: is the only words I can think of. Wires and plumbing going in all directions, looks like a spider web in there. As you look around it even gets better to see what is connected to what. First thing that came to mind was what planet was this manufactured :eek: OR wonder what beverages are in the machines at the plant :cool:.

If you want a good laugh, I highly recommend opening the inters of your rig. When you read posts where members state " Keystone Does not Know how it was installed" you will understand. Do not expect to easily move around in there. its a very tightly woven web. From the prospective of keeping people out and confused "EXCELLENT JOB"

You pretty much summed it up. One needs a thorough understand of AC and DC wiring and plumbing to do much work on a trailer. There are no diagrams or schematics that I know of and I have searched extensively.

Wiring at Keystone is, at best, a "party in the works" and it goes downhill from there. When I rewired the tail lights on my Springdale, I tried to follow the Yellow/Brown and Red/Green wires from the connector back to the lights, but the wires at the lights were black/white and blue/orange (or something like that). Somewhere in the "belly of the beast" they "converted" from one color to another. Heaven help anyone who tried to follow color codes on that trailer. I was "suspicious" until we visited the plant. Here's a few pictures of the "standardized and well regulated" wiring in the Cougars they were building the day of our visit.....

Trying to trace down a specific wire after the belly is closed and all the partitions are installed would very easily make a grown man cry.....

John those pics are amazing. I've done lots of wiring in my time and I've seen a zillion miles more done but I don't know that I've seen anything quite so "thrown together". I wonder how they figured out what's what on the next to the last pic.

JRTJH, Looks very similar to the movie I watched :eek: However looks like the tech on the job in your pictures had been only working on his shift for a few hours (minimum refreshments). I noticed in your pictures that there seemed to be an attempt to form a cable raceway through the rig AND even some evidence of an attempt to route plumbing at right angles. Rest assured that the tech(s) that worked on mine were well into the shift with an empty beverage machine :banghead: Sort of reminds me of the military days and ship yard work. Like I said very entertaining as long as you are not trying to get work done :rolleyes:

I agree. I spent a long weekend and removed a bunch of panels, and traced wires as best I could. I also checked all my fuses and breakers, corresponding them to what they actually operated. Of course they weren't labeled correctly.

But, it was worth it because now I have a paper diagram of all my wiring and plumbing. Sure will help out when/if I need to make repairs or upgrades.

I ran into the same thing when I added a second 30A service to my Outback. I was able to sort a lot of it out and documented as much as I could, there were still a lot of connections that I could not find and probably would not want to. My intent was to balance out the AC loads and I'll just live with the rest of it.

Here it is

Now that's funny, Yak:rofl:

Amazing that anything works on these things.

You pretty much summed it up. One needs a thorough understand of AC and DC wiring and plumbing to do much work on a trailer. There are no diagrams or schematics that I know of and I have searched extensively.

Even with a thorough understanding you will be in the dark, and with most RV wiring systems I have seen lately that is literally in the dark. I have no clue how in the hell they get away with what they do. Reminds me of one commercial project I was on where some clown "accidentally" hooked the electrical conduit from a parking lot light to the sprinkler system... they found out when they turned the sprinklers on and water started spraying out of the timer boxes for the lights. I am convinced all of those guys have gone on to management positions at the RV plants.:banghead:

Hey Yak, that schematic makes sense to me. (tx) It's better than anything the RV manufacturers would make.

[flubyu]

While we're on the topic of wiring, can someone tell me where the power for the 12v lighting goes into the slides? 11 31bhpr. (Tx)

Crawl under the slide, look up and you'll find a cable with a spring attached that runs from the main coach to the slide. It will enter the slide floor. That is the 12 VDC power supplied to the slide.

[flubyu]

Thanks, I'll take a look!

[Hans Jr]

I love Yak's diagram lol

[flubyu]

Looked under my slides but didnt see said harness...?

[chuckster57]

I've seen the 12V feed run through the tubes that the room moves on.

[cb1000rider]

About 10 years ago, for 250k, you could buy an RV that was engineered with stuff like wiring diagrams. I assume the price has gone up.

[srvnt]

Whats really weird is the 110v wires running everywhere, without conduit or even Romex for protection. Scary. :eek: And cheap plumbing parts that can flood your rv when they fail.

[cb1000rider]

I don't know if this will help or not, but you can buy a telco tool called a "toner" that will essentially allow you to do individual wire identification with a wand. It sends a pulse down the wire and a little wand picks that pulse up when you get close to it..

Course, you need to isolate stuff - doesn't work at all for common grounds, but let me know if this might be helpful.

[sourdough]

The above post is correct. If you don't know "what's what" you can purchase any number of instruments that will help you detect one wire, or conductor, from another. In your situation it might be helpful.

YAK.... Now I understand! THANK YOU!!! I couldn't have figured it out without your exhaustive research, you saved me hours "under the bonnet" as the Brit's would say!

Over the course of several campers. I've found my best friends to be McCormick's (5 color) Food Dye, for the plumbing issues, and a "Toner Set" for the wiring. The food color is self explanatory, the toner set will trace out individual circuits, using a tone generator, and a tone finder wand. It's PFM when it comes to finding the "other end of the wire". If you have a friend that works for the phone company, buy him a six-pack and get out of his way! If not, go to Radio Shack, before they go out of business, and buy one!

Keystone seems to have a "one off" approach to their campers. (Don't even get me started on "LABELS"! read that "Fifty Shades of Grey Water") It seems that no two are identically configured, even in the same model, and the same model year! Don't get me wrong, they build a H*ll of a unit, just not consistent in their attention to details. We know more about a particular VIN unit than they do, it seems!

"If in doubt... short it out... find the blown fuse... and your almost home!!! LOL

Sorry to revive an old thread, but found this link during extensive Google sessions. Any validity to it?

https://www.keystonerv.com/media/9143125/12-vdc-wire-standard-keystone-rv.pdfMaybe. It's from 2015 and things change on an as needed basis. 4 years later may be totally irrelevant.

[MarkEHansen]

I think that's still valid. One of Keystone's "features" is that they use specific colored wires for different tasks. It's supposed to make working on the trailer easier. This diagram is the key to those colors.

It is not, sadly, a wiring diagram, but it's the closest you're going to get without making your own.

Looks like some wiring closets I've seen in my days working in IT.
