If you just want to splice into rear taillights on Caravan, and run harness out below liftgate door, you can. Just remove plastic cover in rear corners of cargo area at back of taillights to access wires. Do you have a test light 12VDC?

When I hook up my truck to my trailer turn on my right turn signal my four way flashers come on why is this happening?


Hello Dewey, I can think of three reasons that could cause your problem. The truck pigtail is improperly wired, the trailer pigtail is improperly wired, or the trailer wires are contacting each other that they shouldn't.

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,

fess up and get free answers.

Need to know how to wire in trailer brakes with a battery on the trailer on a 92 jeep Cherokee Laredo


This is the OEM / Factory set up for trailers from my 1990 FSM. Note that they used a flat-5 connector instead of the typical flat-4 plug that 99% of the known universe uses. I don't know if newer XJ's came with the flat-4... The 7-conductor schematic is typical although you'll find that some agricultural / horse trailers are wired differently (click image for zoom)...

Here's a scan of the "instruction sheet" that came with my utility trailer's flat-4 wiring kit. (Retouched for clarity.)

Trailer Wiring Diagrams 4 Way Systems

4 way flat molded connectors allow basic hookup for three lighting functions; right turn signal / stop light (green), left turn signal / stop light (yellow), taillight / license / side marker (brown) and a ground (white).

4%20way%20wiring.jpg 4way_vehicle.jpg 4 way tow vehicle side.
4way_trailer.jpg 4 way trailer side.
5 Way Systems

Same as 4 way system listed above but adds a extra blue wire for brake signal or auxiliary power. Used on pop up camper trailers or utility / boat trailers.

5way_trailer.jpg 5 way trailer side.
6 Way System, Rectangle Plug 3/4 inch by 1 inch 6 way rectangle connectors right turn signal (green), left turn signal (yellow), taillight (brown), ground (white). The red and blue wire can be used for brake control or auxiliary. Use on a small motorcycle trailer, snowmobile trailer or utility trailer. Can also be used as custom wiring on trailers with 3 light/wire systems. See "Tow Vehicle Taillight Wiring" below.

6way_rectangle_2.jpg 6 way trailer side.
6 Way Systems, Round Plug

Round 1 1/4" diameter metal connector allows 1 or 2 additional wiring and lighting functions such as back up lights, auxiliary 12v power or electric brakes. Note: The black (sometimes red) 12v and blue electric brakes wire may need to be reversed to suit the trailer. Check with a test light or VOM. Uses: horse trailer, travel trailers, landscaping trailer, car trailer, etc.

Trailer wiring problem. Tow vehicle is a 2008 Grand Caravan with 4 wire plug. Double checked, plug function works fine. When trailer is plugged to tow vehicle with tow vehicle lights OFF the trailer...


Most likely the brown wire from the trailer connector is connected to a constant battery voltage source, and it should be connected to the vehicle running light circuit, however someone might have wired the trailer connector up that way on purpose so that the trailer does not draw power from the vehicle running lights and possibly damage the vehicle running light circuit. (Dodge/Chrysler vehicles do have delicate lighting systems) Here are some images to help assist you, and the 4 way connector is the same as the 5 way connector just without the blue wire for the trailer brakes.

I want to tow the jeep and need to know thecorrect


Review this information and links:
- Trailer 4 Way System Diagram
- Accesories and Instructions

d456d39.jpg

Instructions
1.) Determine a suitable location for mounting the circuit protected converter in an out of the way spot near the left tail lights in the trunk or on the frame rail, if mounted under the towing vehicle.
2.) Ground the white ground wire by placing the ring terminal under an existing screw attached to a clean metal surface or by drilling another 3/32" hole and using one of the self tapping screws provided.
3.) Disconnect the tow vehicle's negative (-) battery cable.
4.) Cut the in-line fuse holder loop wiring.
5.) Using a ring terminal (3/8 inch for top terminal or 1/2 inch for side terminal), attach an in-line fuse holder (with fuse removed) to the positive (+) terminal of the battery.
6.) Route black 12 gauge wire from the fuse holder to the converter passing under or through the vehicle.
Note: When passing the wire through sheet metal always go through an existing grommet, add a grommet or use silicone rubber to insulate the wire from the hole.
7.) Attach 12 gauge wire to the fuse holder with the yellow **** connector.
8.) Reconnect the tow vehicle (-) negative battery cable. Note: See tow vehicle owners manual for any special battery reconnection and instructions.
9.) Determine if the towing vehicle has a 2 wire or 3 wire system.

2 Wire System
  • Has same bulb for stop and turn signals.
  • Some vehicles have a separate bulb for stoplights but also have a combination bulb for turn and stop. These cars should be wired as 2 wire systems, using the wires going to the common bulbs.
  • Note: Attach the crimp on spade terminal provided to the red stop wire and ground it along with the white wire.

3 Wire System
  • Has amber turn signals, separate.
  • Has separate bulbs for stop and turn signals (both red).
  • Note: Attach red wire to tow vehicles brake light circuit.
10.) Using a circuit tester or volt ohm meter (VOM), determine which wire attached to the left taillight assembly is the left turn wire. Attach the units yellow left turn wire to this wire using one of the blue wire taps provided. Determine which wire is the taillight circuit and attach the module's brown tail / license wire to it with a wire tap. Determine which wire is the stop circuit and attach the module's red stop wire to it with a wire tap (for 3 wire systems only, see step 9).
11.) Route the units green right turn wire to the right side of the vehicle. Determine which wire is the right turn circuit and attach the green wire to it with a wire tap.
12.) Install the fuse into fuse holder and test the installation with a circuit light or trailer.
13.) Secure all loose wiring with cable ties.

Testing Procedure
With the ground wire connected and all of the other circuits attached, attach the ground lead of a circuit tester to the exposed ground terminal of the 4-flat end. Activate the tow vehicle left turn, right turn, tail and stop lights one at a time. Probe the three receptacles of the 4-flat end to confirm proper functions. If testing with a trailer, make the proper connections and do the same test as the circuit tester using the trailer lights. If a function on the trailer lights does not work properly, disconnect the trailer lights, turn functions on vehicle off and recheck function with the unit with a circuit tester. Then check the trailer wiring for potential circuit problems.

I hope help you with this (remember rated this help).

Good luck.

I cant figure out how to wire in a 4prong trailer pigtail to a 91 toyota 4 runner because the break and turn light are not the same wire.


go to your nearest auto parts store and ask them for a connector that plugs in the factory harness. that adapts a 5 wire toyota system to a 4 wire trailer system. thats the easyest way but I can tell you how to wire it up but it's kinda complicated.

What is the best wiring for trailer lights, 4 wire


If the trailer you are using does not have electric brakes you can just use the good old four wire system. Go to a parts store and you can get a neat little plug that you just plug into your wire harness at the rear of your vehicle. This will hook the wires up correctly for you. Then you will be set to tow. Usually the plug costs around 24 to 30 dollars. It is lots easier than splicing into the system if you don't know what you are doing. Trust me on this one.
