7 pin to 4 pin

[captron33]

7 pin on motor home 4 pin on tow jeep grand cheerekee . My wires came completely off. I bought a new 7 pin ( black plastic ) when i hook the wires up as the back of the connector says ie. Black to black, red to red, white to white and yellow to the center position the lights on the jeep don,t work
as they should. What am i doing wrong. Need help.

I have replaced several of the 7 pin female connectors in the last year or so.You cannot go by what's written on the replacement connector.Must be just one chinese
Company making them because they came from different auto parts stores here where I live and all were labeled wrong.
As has been mentioned get a good test light and set down and place them in replacement plug as they should go.

My best guess is the wires were not color coded the same way as the plug.

Using a test light figure out what each of the wires are and connect them per the LT, RT, Tail and Ground labels instead of by color.

The ground (motor home end) is also a major suspect.. Had that problem with my towed.

7 way color code
BLACK--12 volt hot positive
RED--- LEFT Turn
Brown--RIGHT TURN
GREEN--- Running lights
WHITE--- Negative/Ground
BLUE---Trailer Brake HOT
Yellow-- REVERSE/Extra
4 way Flat
White---Ground
Green---Left Turn
Brown-- Running lights
Yellow-- Left Turn
4 way ROUND---whatever the installer decides--that is why round 4 ways are not the best way to go. Too many variables. Doug

ummm, just an observation, but on the 4 way you have 2 Left Turns. for NASCAR maybe:B?

Thank you. Corrected. Doug

You fell for a BAD website. That website schematic is WRONG on the 7 way. Doug

Also note that color codes on socket are mirror view of those on plug.
Since you are redoing whole thing, I would pigtail designated 4-pin socket on motorhome.
Those 7 to 4 adapters are famous for making poor connections.

Most auo parts stores sell test light with probes. Trace out each wire then label it. My new MH had the color code completely wrong. Manufactures extend chassis and rewire plugs.

Wiring color code on the vehicle is not correct. Your going to have to chase each wire to see what is wrong. Easiest way is probably with a test light.

The wires on the jeep may be wrong. What do the lights do?
