Hi, I’m currently trying to wire my light bar to the high beams so when I turn a switch on the light bar will come on and off with the high beams as well as turn off with another switch. I’ve got the schematic all figured out with a relay and all. I just need to locate the high beam signal wire so I can use it as a signal wire for the relay. I drive a 2002 Ford Ranger 3.0L 4wd. Could someone please help me find the high beam signal wire either in the steering column or under the hood. Thanks

 

The light green/black stripe wire at either head light is the High beam 12volts

Fuse 33 in cab will also only have 12volts when high beams are on

High beams are also used with "Flash to Pass", just a heads up, that has power available even with light switch off

Diagram below

 

Fuse 33 is dedicated to basically all the lights. Are there any other fuses just for the brights either in the cab or under the hood?

 

oops, yes, I looked at the power distribution and fuse 33 wouldn't work for you

 

Do you know any fuses that would work for my case or by chance the wire coming from the high beam switch?

 

Unplug fuse 33, I may have relented too soon, lol

See what other lights are effected, should really just be the high beams only that are effected, yes High beam indicator would be off in dash and DRL wouldn't shut off with high beams on
Which is what that page you show says, so fuse 33 only has power with high beams on

 

For all you ranger guys. Fuse 33 is for the high beams. I pulled it and it didn’t affect any of the lights but the high beams would not come on with the switch. I can now use this as a signal wire for a switch for my light bar if anyone is interested i can send the schematic. Thanks Ron for your help.
