Re: Trailer running lights question
 

Reread this thread. I don't know about newer Dodge (I'm partial to them), but ("96 & newer) Ford does have a fuse just for the running lights under the dash with the rest of the fuses.
Those wire colors are only for the pigtail to the trailer lights,truck wire colors will not corresponde to that.

99 Ford F150 had fuse for trailer harness under hood in a small fuse box, Driver side close to firewall away from the big fuse box under the hood.

Had 3 fuse boxes in that truck!! so confusing!!

Re: Trailer running lights question
 

you may have answered this, but did you test without the trailer hooked up. just a test light to the female plug coming off the truck. i have a 95 dodge and will go look at something if you need me to.

Re: Trailer running lights question
 

I have checked (with a 12 V tester) the terminal connections at the round plug, no juice for the running lights. It has to be a #$%&^ fuse .

I have a hard time believing that I have a broken connection or it was wired wrong!!

Thanks

Do the book in the glove box thing.
If not pull and check all fuses one by one.
If no problems add new T connection and harness.

Re: Trailer running lights question
 

Woooooaaahhh. This is not a 4 wire connection? Is this a round 7 wire plug?

Re: Trailer running lights question
 

I have the same plug and they sell an adapter to plug right in for your 4 or 5 wire trailer plug.

When testibng the wires in the round plug make sure you are testing the right side for tail lights, the plugn on truck is in reverse!I have made this mistake before!! :-[

Trying to make this look like the 7 wire plug for Mopar and most others.
Imagine that the notch in the plug is up and you got 6 terminals around the perimeter and one in the center top.

Re: Trailer running lights question
 

MJ is giving you the same thing but in reverse. Depending on which end of the plug you're on.
