SOURCE: Factory installed trailer hitch and wiring

The trailer light harness should be live. If you turn the ignition switch to run and set the turn signal on you should be able to use a test light and watch it blink back at the hitch.
The fuse cavity you are looking at is a battery fuse feed for trailer brakes or trailer battery recharge.
Check the pig tail with a test light and let me know.
Regards,

SOURCE: need wire diagram to hook up trailer lights, truck not factory equipped w/harness,

I'm assuming you're just going to splice into the tail light wiring so that's what these wire colors are:
at the tail lamp 3 way connector:
black and yellow = park lamp
dark green and brown = left turn signal
there should be another connector with violet and black wire for reverse lights.
the stop lights are turned on through the turn signal circuits.

SOURCE: Trailer harness - Red wire has no power

Hi: under the hood in the power distribution box there is a 40 Amp fuse that has to be installed to power up the trailer package. When standing looking from the front left fender it should be at the front right corner, refer to the power distribution diagram on the cover. As well under the box by the spare tire is a plug in type module mounted on the frame. There should be 2 wire harnesses located there, make sure the correct plug in is connected. Hope this helps... please rate suggestion .... ty

2010toyotatundra powerlocks and powerwindowsdo not work


fuse blown.
check fuses.
some cars have circuit breakers on window motors.
if one motor shorts the breaker pops but then resets.
i use a voltmeter to find lost power feed.
its easy.
check voltage to motor, got 12v , when active (swith closed?)
no, then check at the switch, got 12v at switch input and output
with switch active,
yes, then wire is cut from switch to dead motor.
no, then wire is cut from input to switch and fuse.
like that. its not hard at all to use any voltmeter even a $10 meter at walfart.

Left stop light does not work. Replaced light. Fuses ok


the stop lamps are simple
a fuse , a switch, wires, and lamps
if you step on the brake and the voltage at the lamps is not 12v.
then the switch is bad, if there is 12v on one side and not 12v on the output side of the stop switch.
its very simple , flashlight simple wiring,

Where is the trailer fuse located on a 2012 jeep grand cheroke


depends if the person , installing trailer setup
used the factory kit
or just cut in to your wiring.

my 2010 WK has a fuse.
why not say what fails.? first.
brakes
blinkers L and R
parking lights.
and if the cars lights are effected?????? or hazards.

which location, will the fuses are all under-hood.
the operators guide names them all , lost that.

the factory kit comes with trailer relays to add to system.
this protects the system best from trailers that short out.
best is to set it up like that. using real jeep kit.
but we can fix yours. as soon as you answer the questions.
im not posted all fuses for all 4 circuits,

Where is the fuse for Toyota tundra 2002 trailer lights


The fuse is located next to the positive terminal on the battery, it is an odd fuse. You have to use a socket wrench to loosen both bolts that hold fuse in place by clamping down on both sides of fuse legs. Kling, Mississippi.

My radio is loosing preset after turning off ignition. 2002 tundra


If you just installed the radio its possible the power wire for the radio memory and clock is not hooked up to a constant hot 12v source. Also if all wiring is correct its possible there a bad connection or contact check connecters.
I had the first problem with a JVC radio I installed once it did not have clear instructions on the always 12v hot wires.

Just hooked up me camper and when I turn on the truck lights the trailer brakes lock up. Turn off the lights and they are fine. Please help! Thanks, Bryan


The plug on the camper doesn't match the wiring on your truck, when youturn the lights on it is sending 12v to the brakes.

This is the way your trailer plug should be wired if your truck is wired standard.
