Need Help With Recon Light Bar

[DvlDogDmaxZ71]

well i got a recon extreme lightbar for christmas and tried to hook it up. i wired it directly into the 7 pin harness on my truck (2007 nnbs sierra) but i get nothing. i used wire taps so i thought maybe it wasnt getting a good connection so i removed them and checked the wires and they looked they were making a good connection so i got my probe and checked the pins and it lit up the probe. the only thing thats not checking hot is the red/black wire thats supposed to be straight to the battery. am i wrong or is that not supposed to be hot all the time? also is it possible that any fuses blew on the truck? i checked the fuse on the light bar and it was fine. i think its either the constant on or the ground but havent had any luck in proving it. does anybody have any suggestions? has anybody ever gotten a bad light bar straight out of the box?

 

Thanks for any input,

Matt

I had one that went bad after about 60 days or so. Not sure how common it is for them to go bad so quickly. The first one I had was a rampage. When that one went bad I replaced it with the Recon and it worked great. When I was hooking mine up I turned it on the first time and it blew my fuse for the trailer lights. Replaced the fuse and never and any more issues.

Chech the fuse box (under hood)- it might have the two extra power harness roll up and tape next to the fuse box . 1. for HOT wire (Large camping trailer,ect. 2. elec. brakes

 

Note; that how it is on a tahoe 08

you need to hook up your power under your hood, then it'll work! the new ones wont work at all without that 12volt. and check in the fuse block to make sure the fuse is in too!

ill try it under the hood. just doesnt make sense the harness at the trailer plugin is clearly marked 'battery'. i only have this kind of luck with my own vehicle. i can work on other peoples stuff all day long without as much as a hiccup

 

 

thanks for the replies fellas!

i have the "line of fire" brand, and its tapped into the harness in back via splicing... Ive had mine on for going on 3 years and have had no trouble with it, all LED's still work.... I know there are cheap ones out there, not sure about recon but i see trucks all the time where half dosent work , or led's are out ...

[DvlDogDmaxZ71]

well im sure im having either a ground or power issue...im gonna give it another shot tommorrow

Are you hardwiring it all in. I just got a t-connector with a 4 way. Unplugged the wiring harness at the bumper placed the t-connector in and then plugged the whiring harness back into the plug on the bumper. The t-connector had a 4 way that I plugged the light bar into and then just hard wired the revers lights and have not had any problems.

alright...i hooked up that power wire at the fuse block under the hood and put a fuse in it and i dont get any power on that pin at the 7pin connector on the back of the truck....any ideas?

Did you wire the correct red wire to the correct post in the front of the under hood fuse box/block ?

Also GM put in dummy fuses in the trailer fuse postion ( do not know why, ) so check the fuse and make sure it is a real fuse vs the GM dummy.

Im going to try and attach a pdf file for ya, I hope it works

thank you 08 black max, turns out i had hooked up the wrong wire on the truck. my 7 pin is hot now but i still cant get the lightbar to work. i havent checked its fuse yet. its getting too cold to try to work on stuff very long. but at least i am getting power to it now

You have to wire it to constant power, so get some more wire and run it to the battery and the ground needs to be grounded on the battery to or the bumper i just hooked one up then check fuses then check wires the you should be good

Have you got this to work yet? I bought the Xtreme Light Bar as well but haven't started to wire it up yet. I planned on just hardwiring all of it in. Didn't know if maybe you found a diagram as to which wires on the 7-pin that I need to use.

I just got the extreme bar today. I purchased the Curt T harness (55384) that plugs into the 7 pin and gives you a 4 pin outlet so you can plug in the bar but also leaves the 7 pin free. I plan on making sure it works in the next few days and installing it once winter finally leaves

[RyanbabZ71]

Quick question, if I plug the 4 pin into the trailer connector should any of the lights work or does the red wire need to be connected to a hot power source for the bar to work?
