Does anybody know if there is already wiring inside the dash for clock for an 88 xj??? I know they got rid of them in 92(ish) so the radio could take it over, but i'm not sure about an 88. I want to know before i rip into my dash.
Here's a really good write-up. http://go.jeep-xj.info/HowtoDashClock.htm
I wired up a 91 clock into my 96, which did not have the wiring in place. Just hooked it up to the cigarette lighter and a constant.
