Hey guys, can anyone tell me the best way to connect my yellow power cable to the 12v source? i have no idea where to connect it to.

i'm assuming you want it to come on only with ignition switch on. off with key out etc. i usually just run the wire to anything in the fuse block that comes on with key inserted and turned to accessory position. but then again, i'm only partially electrically inclined and stick to mechanical stuff.

Is this a new radio?

I think the red wire is the switched wire (the one that goes off when you turn the key off), and the yellow one is the always on one (not switched) so that the radio remembers the presets and keeps time.

The cigarette lighter is a good choice for the alway on (is it always on in a z?) . also the original radio circuite is good for the switched power source.

I would suggest using the stop/horn circuit for the clock power. Always hot.

Do the Z's original radios have those yellow and red power supplys? if so where do they connect? thanks.

No, they do not.

You need to buy or borrow a volt/ohmeter and do as others have suggested, find two voltage sources. One of the wires goes to a switched voltage source, the other goes to a unswitched source. It's not rocket science, ask one of your local friends who knows a little about electronics to look at it with you.
