Pop-up camper lights all turn on when tow-vehicle lights are on

check for a plate riveted to the "A" frame (towing frame) top or side of frame
find and ask a distributor where it is found

1000 pounds

see the diagram attached. God bless you

Exterior lights are power by tow vehicle, or you can hook to 12Volt battery or charge circuit. When your unit is plugged to hydro you should have one tab on tow plug that has +12vdc coming to it from converter circuit in trailer. Find that with a test light or meter, then when your sure you have proper wire in plug for running lights, use a jumper wire from one to the other to power lights temporarily while you find each problem with running lights .

Only me.but I would not tow anything

I used to own a trans repair business
Your transaxle won't last 80,000 miles ,without towing anything

when towing my camper it seems my running lights do not stay on andmy brake lights and turn signals do not work properly. I can giggle the harness wires and everything works.

Is this a six way plug (six round holes)? If there are six wires coming from the trailer, then the color code should be as follows:

White - Ground
Brown - Tail Lights
Yellow - Left Turn
Red - Stop
Green - Right Turn
Blue - Auxiliary Circuit (Battery Charge, Electric Brakes, etc...)

If you open the plug up that was cut, it is labeled as to which goes where.
TM = Tail Lights
RT = Right Turn
LT = Left Turn
S = Stop
G = Ground
Center = Auxiliary

Call dealer & ask them to run your vin# to see if it came with towing package. They shouldn't mind. If not, you'll have to wire it in yourself.

When you say that you have power up to the camper, do you mean power through the pigtail/wiring harness with the tow vehicle connected?

The trailer harness wiring is the only way to power these exterior camper lights, i.e., through your vehicle. There are no fuses within the trailer for the exterior lights. These lights are only fused from the tow vehicle's fuse box. So either the connections in the trailer harness are open, or they're open at the tow vehicle connection.

Do the turn signals work on the tow vehicle? If yes, then the only other thing to check is the turn signal flasher in your tow vehicle. A heavy duty flasher is recommended.

From the trailer, yellow, white, brown, red, green, is connected to your vehicle backup, ground (frame), right turn signal, left turn signal, running lights, respectively.

The trailer's blue wire is for an electric brake connection to your vehicle.

The trailer's small black wire should connect to the vehicle's hot, 12V lead for the interior lights. The large black wire at the trailer hitch is for charging an RV battery on your trailer, if it's supplied with one. Of all of these wires, only the large, 12 gauge, black wire goes to the 25 amp converter, which is fused, for the inside lights of the camper.

I hope this helps.
