Kenwood TK-730 install question

[LM Industires]

I just picked up a Kenwood TK-730 to install into my chase van. I got it off ebay and can't seem to find anything on the internet showing how to install it. Now I know it is self explanatory, but I have 4 wires coming from the power plug. Two red and 2 Ground.

Is one used for 12 volt power and the other to the ignition? Or both to 12 volt power or just one?

Any Help is appreciated:

Hey Brock,
When you install that radio, just tie the two wires of matching colors together. That connector is utilized for fault tolerance. Hope that helps!
