Wiring harness question

Observer
I recently purchased a 1989 sunlite skyhawk and these are the wires hanging from the the driver side front. They were cut and this plug was laying in the drawer inside. I went to a few places today loking for a new one as this old one is pretty chewed up. Seems no one has a 3 pole flat plug. I realize I can probably buy a 4 pole and just not use one of them. But more specifically, should this be run to my battery on my truck? I am not entirely sure what wire does what and I heard several varying opinions today from various places. I have a two way fridge which seems to be running fine on just the propane at the moment, but does one of these wires carry power to the fridge when in 12 volt operation? It seems everyone I spoke with today was saying turn signals and brake lights but I don't think this camper has all that on top because it doesn't block the existing ones on my truck. Also I don't think third brake lights were part of the equation back the. But please correct me if I am wrong.

That's what I have on mine a. 4 and they only used 3 mine is fine . And it charges my battery to or it looks like you could still get butt connector on the old one,

Yeah I may use the old one but it's definitely seen better days. I am thinking it was cut off for a reason. Any idea what wires control what?

I've also got a Sun Lite Skyhawk, although mine is a bit newer. I'll check in an hour or so when I get home.

light

I'm not sure , one does light, ground , should be power. I think the black is power you might have to follow into the power supply for camper

Wrong

Black is power in AC home wiring. NOT in DC 12v White is power (positive) can be other colors as the green wire. BLACK is always ground on a 12v system (negative). Check you car and you will see this. Most cars have a RED with to the battery positive and always a BLACK to the negative.

My harness is completely different.

What I "think" you have there is green to chassis ground, black to battery ground, and white to battery positive.

Well, I looked behind the clearance lights up top (or running lights) and they are all green to green connections. It has all red lights up top except for the four in the front which are yellow, two at each corner.
The interior lights have three wires:
green w/ yellow stripe
black
white
Coming down from the top of the camper in the sleeve in the soft side I see two whites coupled into one white,
the green with the yellow stripe is connected to a black wire,
and the green is connected to another green.
From there I haven't figured out exactly where it all goes. I pulled the converter today to replace the exterior weather cover that holds the 30 amp plug. I had to unhook the wire from the box to feed it through the new cover from the wire end from the outside. I didn't really think to look at all the wires and see what's connected to what on the converter.
Rangerdog, does yours have turn signals and brake lights or are these just stagnant running lights up top that are on when the truck is running? Also, does it run to your battery or are you using a separate battery in the truck camper?
bill harr, are you saying that you think the black is always ground? I spoke to a guy today that said the white is definitely ground as it is insulated on the plug and the other two are not. Therefore it must be the ground to eliminate the possibility of arcing in his opinion.
I really have no idea but it occurred to me today that if the fridge is 2 way (propane and 12 volt) and I have a power converter (from what I understand this turns 110 power into 12 volt) then it would stand to reason that the fridge may be set up to run off the converter when it is plugged into shore power, not my truck battery or a separate battery. But then I would think it would be a fridge for 110 and propane, not propane and 12 volt. But I really have no idea and my intentions were to run it on the truck battery while driving and propane when parked. I am sure this is simple to some people but I have never owned a trailer for my truck and the truck camper with the 12 volt fridge seems to stump the trailer people when I talk to them. I am just glad the fridge doesn't have a control board that needs 12 volt to operate the safety valve on the pilot.
On a lighter note, the fridge pilot was being a little picky when I was trying to light it the other day but I got it lit last night and put two beers in there for this evening. One on top and one bottom. I didn't see much of a difference in temp when I enjoyed their hoppy goodness, but the fridge was set on 4 and they could have been colder. So I cranked the fridge up to the coldest setting and set two in there for tomorrow. We will see how it goes then.....:)

Crap! I wired my trailer lights wrong! All the diagrams I see for trailer light wiring show white ground! Being as that looks a heck of a lot like a trailer light plug, the person hay have wired it as such!

White is ground, green is running lights, and black is constant power to everything inside the camper. I used a lead wire and a buddy to help me figure it out. Actually, my buddy figured it out before he was done with his first beer. I just handed him beer.

See there - beer does make you smarter. The better the beer, the smarter it makes you, too. Keep those beers coming, I'm feeling pretty dense!
