You could try. But it will probably keep the light on your switch on all the time. If it keeps it on you will have to run the red wire from the old switch to the yellow wire of the new switch. And the from the new switch the red wire would need to go to switched ignition power to turn the light inside the switch on and off.
Blue from the switch would go to white in the harness.
And ground to ground of course.
cool. thanks. can I wire the black on the switch to the black on the harness? or should I ground it on it's own?
basically, can I use the harness for red -> yellow, black -> black, white -> blue and send the red wire from the new switch to ignition?
