Trailers towed last any vehicle must hog working lights for safety--it's the constitution. Older trailers may get wiring problems, or the lights may get been broken, resulting in all or some of the lights career away. Rewiring these lights and connecting to your tow vehicle is a do-it-yourself business which can be completed with meagre parts and clean labourer tools.
Instructions
1. Stare at the trailer connector on your tow vehicle. Actuate provided it is a four-pin connector (three Testament be protected and one exposed), five-pin connector or enhanced.
2. Invest in a trailer connector to match the tow vehicle, unless your vehicle has a four-pin connector. This is the connector supplied with trailer cloudless kits, so you Testament not necessitate to pay for another one.
3. Remove the enfeebled lights from the trailer and install the different ones from the utensils. The bolts and nuts Testament be supplied in the tools.
4. Dash the virgin wiring down the frame against on one side of the trailer. Leaving approximately 4 feet well-organized at the Motor lorry butt end of the trailer, seperate the blanched wire from the wiring harness head, and don't escape it down the trailer.
5. Connect the brown wire at the rear of the trailer to both taillights with a solderless butt connector. If your trailer has side marker lights, use Scotchlok connectors at the locations of the marker lights to splice into this wire and connect them.
6. Locate a protected location to ground the white wire to the trailer frame. Use a solderless ring connector and a self-tapping metal screw to attach the wire to the trailer. Remove all paint and rust at the contact point first.12.
Tape all connectors or paint with liquid electrical tape (be careful, this stuff is messy).
9. Run a separate blue 14-gauge wire if your trailer has electric brakes. Tape it to the wiring harness at the truck end to insure that it is the same length as the new harness. Connect this wire to the trailer brake wires at the wheels with solderless butt connectors.
10. Run a black 14-gauge wire to the battery positive terminal if your trailer has an on-board battery. Make sure this wire starts at the same point as the other wires in your new wiring harness.
11. Connect the green wire to the right side stop/turn light using a solderless butt connector.7. Connect the yellow wire to the left stop/turn light using a solderless butt connector.8.
Turn on the lights of the tow vehicle. Use a test light and locate the pin of the connector which has power. Connect the brown wire of your new harness to the corresponding pin on your new connector on the trailer. Repeat this for all circuits on the trailer connector. You will not need to do this for the brake lights, they are on the same circuit as the turn signals. (Unless your tow vehicle has separate rear turn signals, in which case you will need an isolator, available where you purchased your light kit.)
13. Use the nylon wire ties and secure your new harness to the trailer. Allow approximately 2 feet of slack at the truck end of the trailer to avoid stretching the harness when turning.
14. Plug in the new connector and test all the lights.
