I have a Kenwood KOS-A300 Factory Radio Upgrade System. It used to be in a Honda Odyssey and worked great. Sold the vehicle, but pulled this Kenwood system out before I got rid of it.

It has red and yellow wires so needs to be directly hooked into the fuse box for power. I did this for the Honda, but I am looking to now install it in a 1994 Nissan pickup. Not sure which fuses to tap into though. Is there any way of getting a hold of some sort of fuse diagram for this vehicle? And which ones would I tap into for each wire (red and yellow)?
