Default Radio IGN 12V Issues

Hey folks, I'm having some problems with my 98 Integra GSR Radio.

I was wiring my alarm system up, had no problems there, but I think I may have yanked out a 12V wire for my radio somewhere during the install (it was with remote start). I know its the 12V because I've yanked the radio and tested the 12V with a DMM and got 0V. I unbolted the fuse box to get to some wires easier, and I think the wire was yanked out somewhere Can anyone tell me what wire color I should be looking for and what color/size/shape/#connectors harness plug I should be looking for. Any other thoughts suggestions are appreciated. Thanks guys.

EDIT:
Ok, I'm an idiot... I'm having problems with the ignition wire. No 12V during key to ACC or ON, before OR after startup. Fuse is definitely fine, checked the yellow/red wire in the green plug at the fusebox and at the pins of the fuse. Constant 12V is fine, however it would seem that my head unit is wire incorrectly, and the red (12V) on the adapter harness goes to the yellow/red wire and the yellow (12V switched) goes to the constant 12V (white/blue) wire. Odd how it used to work and now it doesn't. Possible I fried a wire?

If you have no 12V+ output from your ign. switch on acc., [yellow] you have a problem with the ign. switch. 94

No 12V at the ignition wire "after startup"?! Your car will not start up w/out 12v on that ignition wire. You're testing the wrong wire. You need the black/yellow 8 gauge wire on the ignition harness.

Your harness is wired correctly. Yellow/red is your radio accessory wire. My guess is that you blew the fuse, or that you're high on PCP.

There is no 12V at the ignition wire to the radio. I'm talking about the switched 12 V at the radio harness. The fuse is fine, but when I hooked up the DMM to both the fuse's terminal, I didn't get any voltage at all. Any ideas?

My radio harness adaptor wasn't actually wired wrong, I just wasn't thinking right. Its hooked up right, I'm just not getting anything on the switched 12V wire.

OIC, the HUs acc wire, [switched], how about other accessories, do they all work, is there anything else that does not work?

Have you checked main fuses in the under hood fuse box? 94

If you have power at the radios acc. fuse, [fuse 28 - 10A] when ign. is in acc. or run, the problem is after the fuse, you may have "fried a wire", check all the plugs on the fuse box, make sure they are plugged in properly. 94

sorry, i should have been more clear in my last post... no 12V at the fuse's pins underneath the dash when the ign is in acc or run. i meant the fuses are in working order... the problem is definitely before the fuse. all the plugs are in properly. any specific wires i should check upstream of the fusebox?

Have you got 12V+ on the ign. harness acc. lead, [yellow] when ign. is on acc. and/or run? If so, check ign. harness plug at fuse box. 94
