Jesus_man Ahh snap! That would have been a good way to do it! But I am confident what I installed will last a long time as well!

I think I am ok with lighting on the truck with the light and cam in the tailgate, but that is a good idea.

Steve83 For your next trailer:
4-foot with terminal box

8-foot with terminal box

You can tap that same circuit on the truck to add reverse lights to it, as shown on my duallie in a previous post.

Jesus_man Success!! So being colorblind and doing wiring can be daunting, but with the help of my son, I was able to get the trailer project completed this weekend!

1st order of business was to replace the uber-cheap connector that was just 5 wires wrapped in electrical tape with a cheap plug at the end. After labeling everything, I bought a new pigtail and changed out this:

to this:

My son helped run a new wire for the reverse lights thru the existing conduit. Then we soldered and heat-shrunk all the connections and we then wrapped up the new junctions in electrical tape and then fastened them to the trailer. After drilling some mounting holes and zip tying wire up, we ended up here:

Hoping they throw enough light to make a difference, but if they don't it will be easy to swap to something that does. And also hoping this location is protected enough not to get torn off.

I was fairly shocked when i plugged it into the truck and everything worked the first time! Thanks for the help!

Jesus_man They say they are a spot light, but they seem to spread out the light pretty well.

I'm also putting a set on my golf cart that I use around the house. And I put some on a friend's duck boat, and the back of the duallie in my avatar.

I like these because they're rugged, bright, inexpensive, & compact:
Apologies if I seem to be hijacking this thread....

jimmy I added a SPDT switch into that circuit on some of my trailers. The lamps at back of trailer are connected to the reverse light feed from truck or flip the switch and they are connected to the battery charge/power supply feed so I can use them as load lights for getting ramps out or down on the various trailers.

Jesus_man Agreed Steve, I just happened to get that same information on the other site a day before you posted here.
03-14-2019 10:24 PM
Steve83 You could have found that by clicking the diagram I posted above.
03-11-2019 08:44 AM
Jesus_man On another forum, I just found out that there is a reverse light circuit in a 7-round! So that is indeed the way to go! That will be a fun little project sometime when the weather warms a bit.

klhansen You can't get power thru a 4-pin other than the running light or brake/turn-signal. There will be a blunt cut wire for reverse lights just forward of the rear bumper. You could wire a waterproof connector to that or like Steve suggested convert to a 7-pin. I would just go the 7-pin route. Some Ford trucks have a trailer connector with both 40pin and 7-pin receptacles. It should plug in where your 4-pin does. You can find those at a wrecking yard for a few bucks, or even visit your dealer and buy a new one.

Adding LED pods to trailer

I have a car-hauler trailer and I would like to add an LED pod to each rear corner for backing up at night. My trailer is setup with a 4-flat at the rear and it was my initial thought to wire the pods to that and plug in when needed. But then I worry about corrosion when not plugged in and protected. So perhaps I wire in a waterproof switch as well and leave it plugged in?

Or should I forget the 4-flat and just wire it to the running lights and hide a waterproof switch somewhere?

Anyone have any luck with certain waterproof switches?
Something like this?
