RS3200 '02 Tacoma Aux output

Why not get a remote starter and alarm unit all together? It's a lot easier to put in a new unit than hurting yourself with the thinking process of combining the two unit to work. It's not a difficult vehicle to do an install on. Lots of room to work with. You will be done with the installation before anyone here can figure how to combine wire together for you. Trust me, it's not worth the aggravation just to save a few bucks.   Be careful whose advice you buy, but be patient with those who supply it.
