Default wiring a third brake light

just picked up a third brake light from a 94-98 model. but mine doesnt have a cargo light or a brake light. wondering how to go about wiring this thing up. should i go through the brake switch and the courtousy lights? any ideas would be good.

your gonna have to come off the brake switch and run its own wire...you can't "pick up" the brake signal after the t/s switch,or the chmsl will light when the t/s are on

you can come inside and wire it to your courtesy lights...at the dome lamp.

the brake switch..find the wire thats hot when the pedal is depressed....itrs white..i think

oh ok so to wire up the outer lights just run it into the dome lamp, for the brake light to the switch. and if i want an external cargo light switch just wire that up and jump it into the dome light wiring thats at the light?

yep..should work....

you'll need a test lite to find which wire gets hot at thr switch..get a somewhat decent test lite...not a dollar one

well looking at the brake switch the white wire goes down into a splicing with more wires connecting to it. am i correct in assuming this is the hot lead when depressing the pedal?
