I just got one of those Fire and Ice LED tailgate light bars for my 05.

easy install, looks great.

now can anyone tell me which damn wire I need to splice into so the backup led lamps will light up when put in reverse?

 

Reverse light circuit is dark green/yellow.

 

I tapped into the Black with pink stripe and that seems to do the trick.

Now my question is if it is working properly.

The reverse white lights work fine.

When the headlights are not on the left and right side turn signals light up accordingly.

when the headlights are on the entire red strip lights up. But it doesn't blink for the turn signals, just stays
solid is that right?

 

Black with pink stripe at the taillamp assembly, Dark Green with Yellow stripe at the "Trailer Tow relay" (junction box and transmission range sensor); the Dark Green with Yellow stripe can also be found under the drivers side door sill plate.

 

The reason your signals won't work is probably because of a burnt fuse.

 

nevermind gents. the install was perfect. you just have to wait until it's pretty dark out to see the difference when the level of brightness changes when driving lights are on.

I think it looks great.

 

I have the fire & ice recon bar on my 2010 F150 works awesome, everyone that see's it asks how much I paid for it and where to get it.
