I am trying to hard wire a recon light bar on my f-150 and need some help. I have a 7 pin trailer light plug in. Does anybody know what colors i would tie into. To hook the light bar up it has a 4 pin connector on it now. It says you have to cut off the 4 pin connector and one wire is the ground one is the left turn signal and one is the right turn signal. The other is the park lights. What color wires on my 7 pin trailer lights do i hook these 3 wires up too.

 

I forget which exactly... But a 12 volt auto tester is your best friend for a situation like this. You'll have it hooked up in 5 minutes (It's what I did/used).

 

I also have a voltmeter for all my electric installs...saves a ton of time...

I dont have mine hardwired except for the reverse lights....your best bet would be to match the plug up to the holes in the 4 pin connector and then check the colors of the wires behind the stock pin connector...then splice accordingly.

second option would be to wire it closer to your driver side tail lamp....just ground to nearest bolt and then do parking wire, turn signal and reverse.

 

take a look at this, maybe this will help.
