Unfortunately you will need to buy some form of wiring converter. To work with your trailer lights. The problem is that your Corolla has a separate turn and stop signal, Trailer lights have one wire for turn and stop. I suggest the CURT 56175 3-2 converter. You should be able to find it around 20 dollars.

2005 TOYOTA COROLLA WANT TO WIRE UP THE SEVEN PIN TRAILER PLUG TO MY TOYOTA 2.0 D4D LITRE COROLLA


the secret here is to buy a trailer harness for the vehicle ( available from most tow bar supply and fitting shops )
it is a set that just plugs into the existing harness at the rear light assembly ( piggy back arrangement)
from there you wire the male and female plugs as per the color code that is on the paper that comes with the units
saves cutting into the car harness and causing real electrical problems

Wiring Different Trailer Types - Highlander


Hello all,

For those of you that need to wire up a trailer or have to occasionally borrow trailers and look at the wiring plugs with disdain (I mean face it they don't make sense, grd is white, +12vdc is black, etc), this is for you.

Plug Types/Application
7 Way - RV Trailers, Horse and Utility Trailers
6 Way - Horse, Stock and Utility
4 Way - Utility Trailers

Columns are: Color, Function, Mark on the plug.

Seven wire Trailer plugs:

Horse, stock or utility trailers:

White = Ground - 1
Blue = Electric Brakes - 2
Brown = Tail and clearance lights - 3
Black = Battery, aux power - 4
Yellow = Left turn/Brake - 5
Green = Right turn Brake - 6
Orange or Purple (not both) = Auxilliary or Reverse - 7

Recreational Vehicle:
White = Ground - 1
Blue = Electric2_bing.gif Brakes - 2
Green = Tail and clearance lights - 3
Black = Battery, aux power - 4
Red = Left turn/Brake - 5
Brown = Right turn Brake - 6
Yellow = Auxilliary or Reverse - 7


Six wire trailer plugs:

Horse, stock or utility trailers:
White = Ground - GD
Yellow = Left turn/Brake -LT
Green = Right turn Brake -RT
Brown = Tail and clearance lights - TM
Red or Black (not both) = Battery2_bing.gif, aux power - A
Blue = Electric Brakes - S

Recreational Vehicle: (color, use, plug mark)
White = Ground - GD
Brown = Right turn Brake - RT
Green = Tail and clearance lights -TM
Black = Battery, aux power - A
Red = Left turn/Brake - LT
Blue = Electric Brakes - S


Four wire plugs:
White = Ground
Yellow = Left turn/Brake
Green = Right turn Brake
Brown = Tail and clearance lights


Ground should be 10ga.
Others 14 ga

A test light and a 12VDC power source can be handy for trouble shooting.
Best regards
Mike

04 toyota corrolla I need to wire a harness for a utility trailer, not sure how many wires are needed and do I need 1 or 2 lights on each side of trailer. not sure on these newer cars with more than 4...


First and foremost, installing the wiring harness is not the easiest task, but not the most difficult. Typically you will use a 4 pole harness. One wire goes to tail light on, second wire goes to brake light, then one to left signal and right signal. You will need a test light of some sort in order to determine the hot or live wire for each bulb. Once you confirm the wire you can simply splice the wire off the harness into the factory harness. One thing I will mention at this point is using a typical four pin instead of a adapter that are a it more expensive can cause more draw on your cars electrical system. Although I have never had any problems on my cars. I have heard situations in which wires have become cooked.

As far as trailer lights go it may depend on the state. Here in IL, you can get away with running 1 light on each side of the trailer granted all functions work-brake, running lights and turn signals.

Good luck

How to wire trailer lights to a toyota tacoma


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!

04 corolla torque converter code


My 2005 corolla is making a horrible noise and shuddering when it comes to a stop. We just had all the solenoids changed and a new ECM that had been recalled by Toyota. We took it out of overdrive and it stopped the noise and the studdering . There have been no codes on this problem as yet.

Any ideas???

Do u have a 4,5,6,or 7 way (wire) system? If it's 4 way it allows basic hookup for 3 lighting functions:
GREEN is right turn signal and stop light, YELLOW is left turn signal and stop light, BROWN is license, and side marker lights, WHITE is ground.

5way is same as above, but adds a BLUE wire for brake signal or aux. power. Its used on pop up campers, utility and boat trailers.

6way (rectangle plug) green=right turn signal, yellow=left turn signal, brown=taillight, white=ground, red and blue can be used for brake control or auxilary. Used on small motorcycle trailers, snowmobile trailers, utility trailers.

6way Round Plug, same as above, but blue is electric brakes, and black (sometimes red,) 12v; note:sometimes red/black need to be reversed w/ blue to suit the trailer.

7way adds an additional pin at plug in for 12volt power or back up lights. Whoa! hope that answers your question w/out confusing u. Let me know if u need more info.
