Got a Brake hitch Light with 4 pin plug ,all fit well after install but does not work ?? Is there something i have to do under the dash or on the truck to turn this option on ? Let me know if so . Thanks Vinnie M. 04 f-150 FX4 Crewcab.

 

Check your owner's manual to see if there's a fuse just for trailer lights. Also, make sure the front end of your 4-pin harness is plugged in.

There was some sort of a relay that comes with trailer tow kit. It may need to be installed.

 

Thanks for the feedback Steina & rljphx , found the tow kit in the glove box ,installed the relay still does not work , will have the light checked out ,will post on the out come . Vinnie M.

 

i have one of the brake lights you refer to, umn dude check the bulb. nice brake light but its usually a cheap china made light bulb.

 

If it is a fuse good luck getting at it. I had to change my trailer turn signal fuses when both the left and right blew due to a short in the trailer. In Fords infinite wisdom they relocated the fuse box in the passenger side kick panel at a 90 degree angle. You have to contort your body (at 6'5" that isnt that easy) to be able to see the fuses. In my 97 they were conveniently located right under the steering wheel.

 

I'd suggest looking at the bulb also. i picked up a "Ford" lighted hitch cover at autozone, and all I did was plug it in. didn't have to mess with the wiring kit in the glove box or anything. I did cover up the few inches of exposed green and white wiring with electrical tape though.

 

Hey! Hey! Everyone thanks for the info , there was no bulb at all in the light , installed and now works , great thread works well !

Vin -

I guess the bulb was optional at extra cost!!!
