I need to add a trailer light plug to my truck. i need the tail light wiring diagram for a 2005 toyota tacoma pickup.

First check bulbs,Then check to see if your truck has a trailer hitch wiring connector,Sometimes they use a "t" connector to split the wires.Check for broken or corroded wires around the connector.

You need a "test light". Then you turn on the circuit you want to wire in, tail lights, brake lights, blinkers and poke around the back of your light sockets until the test light comes on. Then you splicew into that wire and run it to your plug in. If you don't know which wire is what on the trailer, hook it up and with the wire fastened into the truck harness, try it on the trailer harness wires until you get the proper lights working. Process of elimination. Hope this helps.

you have a short. you will need a wiring diagram and some know how to find it. check the tail lights and anything that isnt factory installed (trailer harness???)

you will need a converter box,..... because a trailer uses the same bulb for the tail/turn signal/brakes where as your truck uses seperate bulbs for turn/brake. Any parts store will have what you need and a diagram to wire the trailer.

The easiest way is to get the kit that plugs into the taillight harness to adapt your plug. If one isn't easily available then you can use scotch locks to splice into your trucks harness. Use a test light to make sure you locate the right wires in your trucks harness and go by the wire diagram on the instructions from the plug to hook it up.
I hope this helps!

He installs it in the video.

hi...

1.may be the bulb might have fused off. did you trying changing the bulb. if not try changing it and try it.

2.may be the wire which connects the bulb have been busnt out before the fuse fuses off.this is occurs because of using wrong grade fuse. try checking the wires are in good condition.

please rate me if the information which i provided was usefull for you. you can rate me by clicking on the thumb icon which is located on the bottom of the page

Tail lights and brake lights are on the same wire.
Connect the wire from the brake light to the connector in the car to the tail lamp wire connector and you will be set to roll

Buy bulk wire and extend the harness, u will need **** connectors and a cheap crimping tool.

Check the taillamp fuse on the truck. If it is blown, you either have a short in the wiring of the camper, or the 7 pin inverter box on the camper.
