clifford matrix 50.5x

Hey guys! I was wondering, I had a installer install my alarm for my car but is really hard to get in contact of so I decided to take things into my own hands. I took out the alarm from a 02 Acura RSX and I'm swapping it into a 03 G35 Sedan. I noticed that there are 2 wires that I believe require a constant 12v. I'm not sure.. but there is a white wire, yellow wire, and etc. RADIO 12V      WHITE/ red      +      radio RADIO GROUND      black      -      radio RADIO SWITCH      yellow/red      +      radio RADIO ILLUMINATE      RED / black      +      radio The red was hooked up the radio 12v, black was hooked up to the ground obviously, and I don't understand what wire would be hooked up into a radio switch or illuminate. I've been doing research for the past month, reading my manuals, and following the wires. I've been trying to follow the wires but they keep getting merged mixed in, and etc. So I'm kinda confused, and I have a multimeter, all the tools required. Can anyone help me figure out what wires would be hooked up to the radio switch and illuminate? And is it okay to hook up the other 12v wire (if it is..) with my other 12v wire? I wired one of the 12v wires already, and grounded a wire. Alarm works fine, it senses shock, door trigger is wired in, and I have to wire the lock/unlock wire and then I'll have two other wires that I do not know where to wire.

Sorry to post quickly but I have a picture that may help..

Correctly speaking none of those wires should have gone to the radio. Look to vehicle wiring for where they should go.

I guarauntee you that these wires went to the radio.. lol. I'm OKAY with wiring but I'm not a guru but I'm pretty confident that those are the radio wires.

Oh no, I didn't mean it in any offensive way at all. I was just making sure that it is the radio harness. Regardless.. I found another 12v constant NEXT to that blue/white wire, it's a smaller gauge just like my red 12v gauge. I don't know, but my installer also has another red wire coming out of the primary harness. So there are like two 12v connections I guess? Should I wire both of them up? I'm fairly new at this but I got the gist of things.

I'm sorry to sound  patronising or insulting but I've pointed you to a perfectly good wiring sheet for your Infinity on this site but you obviously know nothing about the wiring of your 50X so if you want PM me with your email address and I'll download it and email it to you.  If you already have one, stop and find a reputable installer in your vicinity and take your car there and let them do it.
