power and ignition wire colors?

i'm trying to hook up a remote start on my 90 240. i'm way confused, it hought i had it all right.. but nothing.. i need to know where these wires are.. and what color they are...
1. Constant power 12 volot
2. Ignition wire
3. ACC. wire
4. Starter wire
i have the book, and what colros they said they were for a 240.. but i can't get ne response even outta the red/black ignition.. my tester doesn't light u at all.. but my car starts fine, lol i dont' get it.. All these wires didn't seem to b in the same harness to me.. i dunno, thanks
