    Im goin on the road today and I dont have much time to go to the dealer, but i think im gonna work with what ive got and hit the dealer up when i get back. The weird thing about the wiring is that theres a diagram on the cap of the factory connector, but it doesnt match up. I noticed goin to different junkyards to get the t connector wire that my truck was the only one with the 7 wire, all the others had the 4 wire. Your time and help has been very much appreciated.

Hi,
Congratulations on a fine pick up truck. 1999 is an odd year for wiring as Ford put one kind of wiring on one truck built in one factory and another in another factory.
The best and easiest way is to - take down the vin# - take that to the dealer there. Have the dealer print out the wiring diagram for your specific truck. The service is FREE.
Best of it

My trailer that has electric brakes installed and a 7 prong plug connector. My Tundra has a tow package with a 7 prong plug.


One of the vehicles would also need to be fitted with a electric brake controller. If the Tundra already has one fitted then the answer would have a 99% chance of yes.

Go to alldatadiy.com and buy the wiring for your vehicle. Other wise go to the junk yard and cut the plugs and wires out of an exact vehicle. This is the only two ways you will fix it. Exact diagrams or exact plugs and switches.

More than likely it's a problem with the wiring. Check the wiring diagram for the trailer again and make sure the wiring is correct. It does seem like a strange problem, but something similar happened to me when I wired my trailer a little loosely on the connectors. Good luck. http://arrowtrailer.com/new.htm

Tow plug


I take it the blinkers and brake lights work ok when not hooked up to the trailer? If yes, then the wiring to the tow hitch is not hooked up correctly. How many wires to trailer pig tail connection? U can have up to 7 depending on what you tow. Check to make sure these wires are hooked up from the truck to tow plug correctly: 7 wired---
brown-Rt turn and brake light, yellow-backup, white-ground, blue-electric brake, green-tail running lights, black-battery charger, red-left turn signal and brake light. Let me know if u have something other than 7 wire, I'll get the wiring color and source info for u.
