As I mentioned before, all trucks from 84 through 88 and prolly later came equipped for the factory clock wiring. That doesnt mean the clock came with the truck...but the wiring is still there! Again...its a 4 wire plug that has a constant power, keyed 12v, illumination and....guessing a ground. Did you even look for the wires? I wouldnt lie to you...hurts my fingers to frickin much to type this for it to be any fun. I pulled 12v keyed and illumination from this source for my tach long before acquiring the damn clock. Do you not have a way of checking for 12V keyed? If ya want I can go out and tear my dash apart and show you where the wiring is...hell the 87' 4Runner is already half apart...would only take about an hour to get at the rest...
