radio wires

[black91turbo]

The previous owner of my supra decided to put an aftermarekt radio in it. He never got around to it but he did get around to cutting the freakin wires from the adapter. I still have the piece that was cut but i have no freakin idea what goes where in terms of what i have to splice with what to get an aftermarket radio to work. (without blowin shit up) Also there seem to be 3 black wires.....they cant all be ground wires can they??
I dont really have much electrical experience ( or exeprience period) with the supra so any help would be appreciated. thanks

You should really get ahold of the factory electrical wiring diagram. You can buy an adapter to splice onto also at most audio stores.

You could splice back the cut connectors.
Get an aftermarket wiring adapter for the car,
http://66.167.3.133/millionbuy/mb_ai_inskit.jsp
which comes with instructions that tell you which wires go to what.

Or you can get the TSRM (the links some place on this site)
and just splice in the new radio.

If it were me, or Jetjock, I'd solder the wires and use heat shrink insulation to splice the wires. I've had some issues with crimp connectors because I pulled the wires out of the connector when working behind the dash in the past. And definately don't use wire nuts.
