i have a 1998 ford explorer xlt with the base system i believe. it is casette/cd headunit. im trying to add my two 12s and 1000 watt amp. i have the line converter box and im trying to splice into the wiring directly behind the headunit so that i can just stick the box behind the headunit and run the rca wires to the back. i need to know what color wire the remote turn on wire is for the amp and what two wires i can splice the box into. ive looked all over the place and cant find any diagrams that match my truck. id appreciate any help. thanks.
