Raptor electrical schematics

[Zoopster]

Anyone have an idea on how to get a detailed electrical schematic for a 2020 Raptor 351?

Thx...Andy

Yikes, my short answer is good luck. I think they throw the engineering schematics in a blender right before they start to wire RVs lol.

But in all seriousness, I think you can reach out to the manufacturer for a schematic. It will be close to what was actually done. It may show roughly the main components. Then it takes some detective work.

What are you attempting to do? Perhaps some of us have gone thru a similar thing and can give some pointers.

Cheers

Attached is the wiring color codes. Maybe this will help

I think the wire color chart is all you will find. RV manufacturers make “engineering design changes” on the fly, so very few units are built exactly the same, even the same day. I have used the color codes and traced wires to fix a few factory mistakes and had great success.

Keystone owners have been trying to find schematics for their trailers since at least 1996 (when Keystone produced their first Sprinter trailer)… ALL of them have failed to obtain that "golden treasure"... I'd suspect that one more try will end with the same result as the "thousands, hundreds of thousands, thousands of thousands of previous "futile attempts" to sweet talk/coerce/threaten/bribe Keystone out of a schematic....

If someone really wants a headache, try again and put "all your effort" into getting that schematic....

My bet, you'll run out of Tylenol long before the headache goes away (and you still won't have that schematic)...

And then wait for the udder shock and disappointment when the OP opens up the panels and sees the cob web of wires running every which way in the shortest path possible lol.

And if your the lucky tech that gets to troubleshoot....

You both have that sooooo right.... Keystone doesn't provide dealers/techs with any more "schematic information" than they do customers.... I think I've seen one "single page schematic" for the 7 pin umbilical connector, but nothing more from any Keystone product.

As for wiring "cob webs"... Here's one I saw at the factory several years ago. And they are significantly more complex now than they were "way back then"....

Yup, mines that times three lol. I think the newer color coded wires might help...some.

I have used that chart a couple of times when troubleshooting a Keystone trailer and so far they have actually been correct. BUT its all out the window when your working on an older or non Keystone unit. I have some LONG jumpers to check for continuity.

I couldn’t figure out why the light by the dump valves never turned off. It was supposed to be connected to the awning light circuit. Using the color code chart, I was able to determine that the courtesy light on the front (which has a switch) was swapped with the dump valve light. Without the chart I probably would have been stubborn enough to trace every damn wire in the trailer and still not solved the issue. A quick snip, strip, solder, and shrink tubing fixed the issue.

Isn't there a switch in the wet bay, or on the front of the unit?

[NH_Bulldog]

On my unit, the light at the dump valves comes on with the awning light switch. The front courtesy light is powered all the time and is controlled by a switch on the light fixture itself. It was wired backwards where the dump light was on all the time and the courtesy light was controlled by the awning light switch. Another post on here from a couple of years ago got me on the right track and the wire color code chart helped me identify and fix the problem.

Ah ok. Well glad you got it resolved!

Thanks everyone. I have the color coded chart. I have reached out to Keystone, and like some indicated, no way Jose. Allegedly the schematics are Proprietary Info. Seriously. The wiring is a mess.


Anyway, I was just hoping someone might have had luck getting a schematic so I don't have to crawl around and figure wiring out the old fashioned way. Everything is working fine on my rig. Just something I was going to add to my notebook for future reference if needed.


Thx, Andy

Many "new rv owners" have a misconception that their rv should be treated like an automobile with regards to how the dealer operates and obtaining wiring or plumbing diagrams.

Let's address the wiring diagram. Auto manufactures use wire looms that are made for whatever model they are building. The wiring loom has specific lengths, shapes, attachment points, and plugs for each device or accessories. Each car has the exact same configuration and it's fool proof for the person on the assembly line so that say a door lock cannot be plugged into a window motor.

When an rv goes down the line it's treated more like a house or building. If you look at a set of architectural plans for say a house and go to the electrical plans you would not see a drawing of say a dishwasher that has a wire that feeds it through cabinet A, down wall B, then into the distribution panel to the "second 15 Amp breaker from the top on the left side". There would be a symbol for the dishwasher and most likely a note something to the effect of "connect on dedicated 15 Amp circuit". Same with the plumbing. It's the responsibility of the trades to deliver their work per the local and national codes. The general contractor has a site superintendent that oversee that work and prevent the trades from getting in each others way.

To get a drawing of a house that's completely accurate is called "as built drawing" and is a very expensive document as the architect of the plan set would have to be on site for every major step of the construction to document every facet of the construction. This is rarely done unless it's absolutely necessary, most commonly for certain types of labs or research rooms, some hospital areas, etc.

On an "average" rv line (not a million dollar bus chassis) they run a power wire from a breaker to the air conditioner the "best way" they can. The relatively recent use of color coded wiring is a huge improvement but I don't think we'll see anything beyond that at least not for many years. High end motorhomes typically have more sophisticated electrical systems and due to the complexity more care and attention buy a "more qualified" installer is involved and is reflected in the cost.

The purpose of this post is not to defend any manufacture but hopefully to help explain the difference in the construction/assembly.

I think you need to contact the Thor headquarters and have them send you a schematic on your TT. They sent me one via email on my new Hurricane 34j Motorhome. I had no problem getting one from Keystone when I had my Premium 19fbpr. You may have to get a resolution specialist to get it for you. It is NOT Proprietary.

Wow BadManRick!! I also tried pretty aggressively to get a schematic out of Keystone for my 2020 Cougar 29RLD. I got nowhere.

Maybe I need to find a different approach?

If anyone should have such a document on a Cougar 29RLD I would appreciate a copy.

If badmanrick would scan and post the schematic Keystone provided him, no doubt many members who have that trailer model and/or similar RV's would benefit tremendously from the information....

Keep in mind that if there is a wiring schematic, and if you can get your hands on one, it is highly unlikely it is anywhere close to accurate. All the schematic is, is a plan on how an engineer planned the wiring, not how it was actually built (that would be an as-built). There is too much ability to make changes on the fly as these things are being built. I looked at 6 different units before we bought ours, and not a single one was wired the same. Location of switches, location of lights, location of thermostats, location of speakers, different appliance brands, etc. Keep an open mind and don’t rely on what you get being accurate (if you can actually get it at all).
