There are many
place you can put an accessory light switch. Alot of switches involve
drilling into dash. I don't mind backcountry pinstriping, a few
dents... some rock-rash... but drill into my dash? Are you nuts?!
Alot of TJ owners who don't have factory fog-lights, rear wiper,
or rear defrost, have three nice accessory switch bays totally open.
For my rocklight, it was either these factory locations, or the
IPF adhesive switch. The dealer is asking $23.00 for the factory
switches! I chose the IPF switch. Either way, where you put your
switch is entirely up to you.
