pink constant wire dodge caravan

I'm installing a new deck into a 1997 Dodge Caravan without a wire harness.  Everything is hooked up and I got it running by hooking both the yellow battery wire and the red power wire to the Dodge's switched 12 volt, but running it like that won't keep the clock set after I turn off the car.  After testing the pink wire that the 12volt.com wiring diagram said is the constant with the multimeter and getting nothing, I need help, please.  A while ago I installed a deck into a 1989 Dodge Dakota and actually had to run a new wire to get a constant  12v from the battery.  What is wrong with Dodge's pink wire?

Is the fuse blown, per chance? Gus Wherever I go, that is where I end up......

I checked a few of the fuses already, do you know the fuse that would cause that?
