Wiring problems

[Idratherbefishi]

I'm new here and I am in desperate need of information. I didn't inherit a travel trailer, but I inherited the maintenance on one. The husky puppy seemed to enjoy chewing on the wiring under the left rear corner and now it's my job to fix it.
There are what I believe to be two black plastic tanks under the trailer, each with orange, yellow, and green wires hanging out of them. Are these wires for pumps?
There is a conduit with a bundle of wires in the area containing red, white, black, green, and brown wires. All these are chewed up.
The travel trailer is a Fleetwood Pioneer, built in September 2004. VIN is 1EB1T182956008981. The overall length from hitch to tail lights is about 23 feet. I believe it is a 2005 model year 18T6.
Is there a source for any literature or service manuals?
Wiring diagrams would be fantastic.
Any help in identifying these wires so that I can reconnect them would be appreciated.
Thanks.

Email manufacturer with vin number and ask for wire diagram for 12v system and tail and marker light diagram. Worse that can happen is they say no.

Here is typical trailer lights Wiring diagram

OK, so where can I get a wiring diagram?

[enblethen]

Yes, 120 volt wiring is normally accomplished using Romex style building wire and is solid conductors. 12 volt DC wire is normally except for brakes accomplished using individual conductors.

In all likelihood, yes.

I know little about this camper. It's not my camper, but now it's my problem.
It was dragged onto my property a few months ago after the owner passed away and at that time, all the exterior lights worked. I'll have to hook up to it and check the lights.
The six (three from each tank) wires coming from the tanks don't show any signs of being chewed, they're just cut and stripped to the same length. Maybe I don't need to worry about them.

I think they're for taillights. Do they work?

[time2roll]

The sensors don't always work that well when they are connected. Does the water pump work?

Otherwise buy some like size and colored wire and connect same to same and complete the circuit.

Or we may need a picture. OK to check what fails to work to help identify what you are talking about.

if your not handy,with a soldering gun and some shrink tube? find a trailer shop or a friend and have it redone. its not hard theres U tube to give you idea,s

The orange, yellow and green are likely to be tank level wiring.

White is commonly ground, black is 12 volt positive, green is right turn and stop light function, brown is tailights.

Generally if you have tanks with Firly fine (Small) wires coming out of 'em those are the level sensors.. And on waste tanks (The black plastic tanks are usually waste) they really are useless after first use so don't worry.

But they go to an epoxy block called a resistor pack From there one wire goes to your sensor panel. Each tank has its own resistor pack and lead to the sensor panel. ONE sensor lead (usually the black and it is the BOTTOM one) will go to ground. Usually a ground pad on the sensor panel

And as I said. they basically work.. ONCE.. Now if you have SEE LEVEL sensors (After market produt) That works Period. but the wireing is different.
