Re: wiring.....for constant

One should be hot all the time, and one should be hot on accessory. Both of these should be available in the fuse box.

Re: wiring.....for constant

red on the head unit is most times power switched, for use'n the radio
the yellow is hot 24/7 for the clock and station memory, some will also have a gray, that ties into your dash lights, to dim the radio with the dash..
good luck
