Newbie here so please take it easy on me, first time wiring a amp and want to get it right the first time.
I have the unit mounted and ran the wiring but not sure what connections go where.
No, you do not need to order the replacement harness, just use the FAST Harness that you have.
Connections will go as follows;
Red Wire - +12v constant of the headunit
Blue/White Wire - switched +12v source (usually the amplifier remote of the headunit)
White - Left front positive
White/Black - Left front negative
Grey - Right front positive
Grey/Black - Right front negative
Make all the connections at the headunit. Prep and connect the ground and you will be good to go.
