Yes, it is possible to convert your 7-way on your trailer to a 4-way. To replace the wiring on your Coleman 10 Foot pop up camper we offer wiring adapters that allow connection of different formats of trailer wiring. The best option to change the…

To determine where the problem is first disconnect the trailer from the tow vehicle. Use a circuit tester such as #PTW2993 or a meter if you have one to test the vehicle side trailer connector while the head lights are on. If there is power on the…

Trailer wiring generally uses 16 gauge wire, part #16-1-1. However, with a long trailer like yours you may want to go with a larger like 14 gauge #DW07550-1 or even 12 gauge #12-1-1. Each size is sold by the foot. You will need to have the lights at…

It is likely that the red wire on your old lights is the turn signal/brake light wire, and the black wire is the running light wire. That would make the white wire the ground. You can verify this by testing the wires using a circuit tester such as…

The brown wire for your trailer wiring should be for the running lights while the white wire should be for ground. Typically clearance lights use black for power and white for ground, like part #MCL32AB, but in the case of black and red wiring the…

A leaf spring should be replaced if it is badly rusted, has cracks or breaks in its leaves or if it is sagging. A 14-year-old travel trailer could certainly be in need of new leaf springs. The keys to selecting correct replacement leaf springs are to…

For the clearance light part #AL91RB we have the grommet part #A91GB which is basically a hard rubber.

There is a difference between a 7-way round and and 7-way rv blade connector. If you take a look at the accompanying photo, which is from our linked article on trailer wiring you can see that the connector on the left has blade-style pins while the…
