My Trooper is not equipped with factory fog lights. When I purchased the vechicle, someone had installed fog lights on the vehicle. The lights are in good and correct working order. If the headlights are not on, the fog lights won't work and the red indicator light is not illuminated. When you turn the lights on, fog lights work and also cut off if you place lights on highbeam. Everything is working correct and fine.[img]smileys/smiley4.gif[/img] The current switch is a 3 prong red button rocker switch. Now the problem[img]smileys/smiley6.gif[/img]. I purchased a factory foglight switch (black pushbutton). I have no wiring harness and don't know what wire goes to what terminal. Anyone know or can help??????[img]smileys/smiley5.gif[/img]

Is good to remember that troopers are equipped with high Amp batteries, severe risk of fire is allways present when wrong wiring occur. If the switch doesn't come with wiring instrucctrions, is safer to hire and expert

isuzus already have the wiring harness built in the body,its located behind the left upper side of the dash.behind the blank spaces or cut-outs.you would also need the o.e fog lamp relay to put in the empty slot for the underhood fuse box. there should be fog lamp harneses for the lights also ready to connect behind the fog lamp cut aways.as long as someone didnt butcher them up connecting the afetrmarket ones.......but to connect the o.e. fog lamps the truck is pretty much already wired up.when you purchase a kit from a dealer all it is ,is a switch ,relay,fog lamps.
