Thanks for the information Tony! To operate your 1994 Coleman pop up's tail lights and power the 12v accessory circuit to charge your battery you're going to need to use a 7-way connector. Only a 7-way connector can send the reverse signal from your tow vehicle and charge a battery.

I have a solution for you but we do not have a simple 7-way adapter that is compatible with a square 6-pin plug. What I recommend doing is replacing your 6-pin connector and rewiring it into the etrailer Trailer Wiring 7-Way Upgrade Kit w/ Junction Box and RV Style Connector item # e99011.

The etrailer item # e99011 includes a 6' long 7-way cable and a convenient weather proof junction box. You'll be able to use the junction box to rewire the square plug following the wiring orientation below:

Black Terminal - 12-volt power
White Terminal - 8 Ground (-)
Green Terminal - Running Lights
Red Terminal - Left Turn Signal
Brown Terminal - Right Turn Signal
Yellow Terminal - Reverse Lights

The wiring colors on older trailer's don't always follow the standard color and function, like I listed above. I highly recommend using a circuit tester like item # PTW2992 to identify the functions on your 6-pin connector to ensure you're wiring them to the correct terminals on the etrailer item # e99011 junction box.

To wire your trailer's battery to power interior lights, you'll need a switch like the Pollak item # PK34513. You'll want to use the 10 Gauge Wire item # 10-1-1, which is sold by the foot to connect the switch to the lights and the switch to the battery. You will then end the wire at the junction boxes black 12v terminal. Some where between the light switch and the junction box you'll also want to add the Circuit Breaker item # PK54220. This will prevent any current overflow going to your lights. You can use quick splices item # SWC501915-1 and butt connectors item # 05732-2 to make the necessary connections.

What kind of tow vehicle do you have and does it have a 7-way connector? Feel free to answer this and throw in any other questions you have, where it says Add Comment.
