I am trying to wire my truck for a 2002 Lance 845. I have the plug socket mounted in the truck bed and now I need to wire it up. The question is what wires do what? I have a Round 7 pin. With the following wires Heavy gage black and white. Then 12 gage RED, GREEN,BROWN,YELLOW. I think that black is hot from batt. Heavy white is ground. The green brown yellow are just like a flat 4 and the red is for the back up lights. Am I right?
Thanks,Mark

I thought that autos were the opposite of house wiring, black grd., white hot.

kp,

This is how my '96 Lance came from the factory.

Holding the plug on the camper, looking into the female terminals, with the plug "notch" at 12 o'clock:
1:00 = not used
3:00 = right turn
5:00 = left turn
7:00 = positive 12 volt (+ battery)
9:00 = back-up
11:00 = running lights (parking lights)
center = negative 12 volt (ground)

So the plug in the truck bed is the mirror image.
Holding the truck bed plug, looking at the male terminals, with the plug "notch" at 12 o'clock:
1:00 = green (14 ga) - running lights (parking lights)
3:00 = yellow (16 ga) - back-up
5:00 = black (10 ga) - positive 12 volt (+ battery)
7:00 = red (16 ga) - left turn
9:00 = brown (16 ga) - right turn
11:00 = not used
center = white (10 ga) - negative 12 volt (ground)

Good Luck,
BradW

In campers Black is hot and White is ground.

I do not have a Lance and BradW's 96 MAY be the same as your model, however, here is what my camper is and what I understand the trailer plug standard to be (using BradW's approach but not colors as they seem to vary wildly):

So the plug in the truck bed is the mirror image.
Holding the truck bed plug, looking at the male terminals, with the plug "notch" at 12 o'clock:
1:00 = brake
3:00 = right turn
5:00 = charge
7:00 = tail lights
9:00 = left turn
11:00 = ground
center = backup

If you can't find wiring diagrams for both truck and camper:
It is really important in your wiring that you identify the ground and the hot in the camper and the truck (because you don't want to plug either combination of hot into ground). You should be able to do that with either a VOM or a test light (don't even try to plug anything in until you make that determination - test only the truck wiring (you can ID all the truck wires this way or only the camper wiring). After that, you can hunt and peck with the turn signals, etc (e.g. try the Left turn and see which one you need to plug into to get the LT to flash.

Good Luck

That is troubling that our plugs differ. Truck camper manufacturers should get together and agree on a standard pattern.

10-4 on that standardization BradW,

It seems like there is a "standard" for the trailer hitch plug that comes with the truck. I have plugged a couple of trailers in and they work. If campers all used such a standard, when I ordered the camper wiring from the factory, I could have gotten a plug wired up in the bed instead of a pigtail hidden under the bed.

Email Lance and they will tell you exactly what it is.

Also do you have the manaual? They have it in there.

Mine goes this way and probably for yours:

Black 12V pos
White Ground neg
Green Running Lights
Red Left Turn Signal

White is often ground in truck wiring also, but devices such as radios mostly use black for ground, so you have to watch it. For trailer wiring, +12v can be any color, but black or red are most likely for your truck "battery charge wire".

Here is a picture that can be useful -- it shows the generally accepted standard wiring for 7-pin trailer recepticals and plugs:



The picture of the factory Ford trailer plug is perhaps the most helpful. Dodge and Chevy use exactly the same standard. Wire your camper receptical up so the wires are in the same locations as shown, and then check your camper plug to make sure it follows the same standard -- and rewire it if necessary to make it compliant with the standard. To figure out the colors used in your truck, you can crawl under the rear bumper, and expose the wiring going to the trailer plug to see the colors.

The new Chevy's with the heavy duty towing package already have a "pigtail" (about a 3' long bunch of wires) tucked up above the frame at the front of the box on the driver's side -- just drill a hole in you box at your desired location and add a 7 pin receptical. Colors are given in the owner's manual.

In the new Dodges, colors are not give in the manual and due to the way the rear trailer plug is made, it will be easiest to use a VOM meter to figure out which wire color serves which function. Also, the Dodges use really small gage wire for their battery charge wire (probably 16 gage), so you will need to bring back a bigger battery charge conductor for your camper. A 10 gage wire with 40 amp fuse run directly from the battery is adequate. You will probably want to add a solenoid battery isolator switch at the same time.

The Dodge further complicated things by running 3 wires that have identical color codes (white with green stripe) to the back of the truck. One of those runs the backup lights. So you need to find the right one when splicing in your camper plug. Of course, on the one I just did for my friend with the new Dodge, third time was a charm (I had to strip some insulation off each one and test it with a meter while my friend put the transmission into and out of reverse to find the right one).

Rather than use those crimp on connectors (which can cut some of the wire strands), I prefer to strip a little insulation on each of the wires I need to splice into, wrap the wire I am splicing on around the stripped area, solder the connection, and then tape it for insulation. I suggest using plastic wire loom to protect all new wiring from vibration and physical damage, or if that is not possible, spiral wrap the new wiring with electrical tape.

Somebody mentioned that a 7-pin receptical is about $50 from their Lance dealer. Yikes, I hope that cost is installed. My Lance dealer (Curtis Trailers, Portland OR) sells 7 pin plugs and recepticals for $6 each (OEM packaging, no instructions).
