Fog light wire colors
Well I kept myself busy today and one of the things I did was cut and mod in another fog light switch to run some offroad lights off of. I managed to get the wire harness to go with it and was curious if anyone could tell me what the wires were previously wired as. There and 4 wires, LB/BK, Black, RD/BK, and TN/OR. I already have the relay I will need for this setup. Thanks for the help.

So Bob how would you suggest I wire this then. I know you have already done something similar which is where I got the idea so thank you for that. I see I need to ground the black wire and illuminate the switch through the RD/BK wire at the insurment panel. As for the other two wires I am a lil confussed. Thanks for the help tho!!

Here is a possible way to wire auxiliary lighting to operate through a factory Ranger foglamp switch using a common automotive relay. It is critical that the two 12v sources are adequately fused and that large enough wire is used, especially for the constant 12v source to the relay and the wire from the relay to the lights. This depends on the total wattage of the load which can be converted to amps. (amps = watts/12v). Also the relay must be of adequate amp rating to handle the load.
The diagram has a flaw, though. The wire to pin 6 is coming off of the heavy wire to the lights. It should have a fuse in it that's correct for the smaller wire to the switch and then to ground.
Where it says "Keyed 12V", it would be possible to substitute other triggers like the high beam wire or the headlight/parking light 'on' wire.
Pin 3 LB/BK
Pin 4 BK
Pin 5 RD/BK
Pin 6 TN/OR

EDIT: I forgot to mention the lights are 55w halogens

That just powers an LED that draws 20 or 30 mA.
I would use a 5A inline fuse to pin 6 and position it on the powered end of the wire - in other words, where it begins at pin 87.
~~~~~~~~~~~~~~~~~~~~~~
Assuming 2 lights @ 55W each, the lights will draw (2 x 55) / 12 = 9.17A @ 12 volts
I would use a 15A fuse in the 14ga wire going to pin 30 of the relay. The fuse should be positioned as close as possible to the powered end of that 14 ga wire.
