Wiring problem

[Chasin Tail]

Hey yall I just got done hookin up my newL.E.D. taillights on my boat trailer and everything works except for the parkin lights. Turn signals, brakes, and hazard flashers all work fine, but cant get running lights to come on. Got the trailer hooked up to the truck all my grounds have been checked and rechecked and still nothin. Anyone got any ideas.

We were having that problem with our old trailer last year. We bought new adapter plugs (7 way round to 4 way flat). Kendall wired in a new harness and flat plug.


....and it ended up being a blown fuse in the truck. [:@]



Check your fuses before you rewire everything.

Ifyou're using a standard 4-flat connection, see if the brown wire goes hot (+12vdc) with respect to groundwhen you have the taillights on.
It should be 0vdc to ground when the lights are off.

How did you connect the car/truck to the plug?
Using a 'T' connector that just plugs into the existing wiring harness, or did you have to chop into the truck's wires individually?


Thislink is a pretty good resource too...
