alrite. so i got me a light bar for the tailgate and i was jus gunna hook it up to my trailer light plug in. Well i plug it in and nothing. so i look down there and theres a white wire that seems to be a ground wire and its grounded to the bottom of my bumper but then it isnt connected in to anything. its just hanging there. I'm more than willing to bet that this is the problem but can anyone tell me where it hoox up to?

 

theres 33 members on and no one can help me? The trailer hitch is the one that came from the ford factory.

 

the reverse light wire in your tail lights. the 4 pin trailer plug doesnt have a reverse light plug so you have to tap into the tail light

 

you totally lost me buddy. the light bar doesnt have a reverse light. And i just found a random wire thats grounded to the bottom of my bumper that wasnt connected to anything else.

 

this thing?

if you just found a random wire. then its probably just that, a random wire that means nothing

 

yes that in the picture. Well i just can't imagine a wire being grounded to the bottom of my bumper and being stripped on the other side but just not plugged in to anything being just a Random wire. i even broke out the tester and theres no power gettin to the running light plug. i believe that that wire belongs in that circuit. Does anyone else have a white wire grounded to the bottom of their bumper?

 

does the white wire come off of the light bar?

 

no he has just the one that lights up. try pming rwenzing hes the man at electrical stuff

 

NOOO!!! lol the bar has a 4 prong connector on it. This wire was just hanging down from my bumper!!!!!!!! I wish i had a good camera right now. This wire has somehting to do with the electrical on my TRUCK. Its grounded to my BUMPER and it used to be connected to something but it has come unconnecte and i need to know where to reconnect it.

 

its probably nothing. i bet the old owner of your truck had reverse lights on the truck and took them off leaving the ground wire.

 

well then this is just ****ing great. Just like the title of my post says!!! So do you know if there is a fuse for the trailer light connector?

 

yes there is a fuse for the trailer plug. if the fuse is fine you might have to check the wiring to make sure its all still in tact

 

well i didnt get a manual when i bought my truck so im gunna aggrevate you some more. lol what fuse is it buddy?

 

White wire grounded to the bumper = ground wire for your trailer connector. I'm going o guess there is only 3 wires going into your trailer connector, as the white one is supposed to be molded in to where the unshielded prong is on the plug.

If the 3 wires (Yellow / Brown / Green usually) are on an extension cable sort of thing, coming from the T harness that connects to inline with you taillights, you can just get a new extension, and use the ground that came with the new stuff.


If it goes in to the T harness, you'd need to get a whole new T harness if it can't be reconnected to it.

 

thnx man. all the wires are hooked up to the trailer connector. so im gunna inspect the harness today.

 

Yep, the white wire is the ground wire. The "T" connector that came on my truck went bad about after a month I owned the truck.

 

ite. well my t-connector wasn't bad. i tested everything again and its all hot and good. The light bar is acting up. It turns on when i turn on the running lights, then if i hit the brakes it cuts off. If i have the running lights on and hit left blinker it makes the whole bar flash. If i have the running lights off and hit the right blinker it works fine but the bar cuts off if i hit right blinker with the running lights on. Anyone Heard of this before?

 

yeah, i think im just gonna get my money back for it.

 

Look at the trailer connector. I bet it is all corroded and messed up. That will do it every time. Also, if you don't have the trailer connectors ground wire connected to anything, it will also really mess with LED's.

 

well i even tried holding the ground wire on a screw on the light bar and it still wasn't working right.

 

check your fuses for you conector had the problem a wile back

 

This is screaming corroded connector or ground problems. I really doubt there is a problem with the lights.

 

your trailer harness is bad go buy a new one! and a multimeter is your friend or the professionals.

 

NOO. and yes a multi meter is my friend because i seriously doubt that the three vehicles i plugged it into all have corroded trailer connectors. It's jus the light bar. Its not a big deal, im gettin my money back anyways.
