Lance 6-way Truck Camper Wiring Video 

Great idea Spencer! Especially since you need both plug-ins.

Glad it worked out for you!

Bless you as well Hugo! Glad it helped!

Good point. Thanks for the feedback. I will make that adjustment.

Lance campers have a built in battery isolator. When the truck alternator reaches 13.2v it will charge the camper batteries. When stopped, the battery isolator monitors the truck battery. When the truck battery reaches 12.8v then the isolator disconnects from the truck battery, thus ensuring it doesn't drain the truck battery.

@@T0DDS is this true? If so then I do not need to unplug my camper every time I stop for awhile, right?

I have not confirmed this either but I will this spring.

@@seancampbell6845 Look under the kitchen sink. I see a device called a Battery Separator then you should be good. Mine has one and it's Model 1314. I contacted Lance to confirm.

Good question Greg. Short answer is, I’m not sure. Others have posted indicating there is a relay that prevents draining the battery when engine is off. I believe this to be true because my fridge only runs on 12volt when engine is running. Once engine is off, it has to run on propane or AC. In my opinion, this makes sense. I have friends who only have AC/DC refrigerators and theirs can run on DC with engine off. They have portable solar panels to manage charge. In order to accurately answer your question, you would have to determine fridge draw verses alternator charge. In my opinion, your alternator should be able to keep up with the fridge draw while engine is running. If it’s draining your battery faster than charging via alternator, I would say something is not right. However, I bought the upgraded HD alternator on my truck. Compare fridge draw with alternator charge specifications and go from there. I hope this makes sense.

When you check all of the lights at the plug in that you newly installed, do you have power to everything as there should be? If yes, sounds like a bad ground on trailer. If no, sounds like something got wired wrong or the connection isn’t good on one of the wires.

You can but I prefer to run the extra wire since you are already running the positive. Sorry for the delayed response. I only check this every once in a while. Glad it helped you out! Happy Camping!

Also…the two wires running from the battery are for the fridge so you do need to run a positive and negative. There is a ground wire in the wire harness that grounds to frame at rear bumper. I hope this makes sense.

@@seancampbell6845 I don't understand why the ground makes a difference to run to battery or the frame since they are one and the same, right?

@@teamboyd1 it’s what the fridge manufacturer recommends. You can get resistance from frame ground and corrosion can cause failure on frame ground. Fridges are expensive to replace so it is more safe to run the ground to battery. Just my opinion.

@@seancampbell6845 your opinion makes sense. Now I have to run more wire. :)

Can you confirm what is and isn’t working once you plug the camper into truck bed female 6-pin receptacle? I would start by testing each pin/spade of each component again. Start at bumper and test , tail, turn, aux, brake, etc. Then test 6 pin female where it is mounted in truck bed. Make sure everything matches up with the layout in Lance manual.

Thanks for getting back to me When camper is plugged into my new truck side plug nothing on the camper works. I tested each of the pins in the new truck side outlet and they are each functioning correctly I have also tested my bumper and truck bed (factory set up for 5th wheel or non- lance TC) 7 pin outlets. They function correctly. As I said. Bewildering.

@@robertgraham-yg7ur sounds like a ground issue because nothing is working. Really odd that you test the truck side plug in the bed and all pins work but when you plug camper in it does nothing. Is your camper battery kill switch pulled out, allowing power to camper?

@@seancampbell6845 I checked the kill switch, it is in. The harness ground is to the frame and checks good. The 8 gauge wires are to battery and check good. I wonder about GFCI in camper being unhappy. I’m about to try it with camper batteries disconnected

@@robertgraham-yg7ur my camper kill switch had to be out in order for my camper to have power. The thing I can’t wrap my head around is the fact you have power to each pin in 6-way in the truck bed but when you plug camper in, nothing works. There has to be a circuit that is tripped in camper where plug ties into electrical. I wish I was there to help. I can give you my cell. Maybe we can troubleshoot over phone.

Sorry for the delayed response. I only check this occasionally. I will get back to you on that tomorrow. I need to double check what I did. Off the top of my head, I grounded it to the frame.

Ok Fredrick, I just confirmed the white wire was grounded to the frame. The red and blue were capped. Sorry about the confusion. I’m not a real good RU-vidr. Just hoping to help others out there. I hope that clarifies things.

@Fredrick did you have and issues with the running or tail lights before you grounded the white wire?

No issues when I finished install
