Immusicman,
There will be a large harness with all the speakers, power, ground, illumination and remote turn on wires, a harness with a power antenna and a (mute – not used) and another harness for the subs. The sub harness has white and grey wires along with a remote turn on wire. You can hook both whites and grays together in both harnesses, then splice them into the same wires that come from the new source unit you bought. It is rather straight forward. As for knowing what is + and -, the wires in the harness (the ford premium and the source unit harness) with a black stripe are always negative. So when you are done wiring all 3 new ford premium harnesses to the new source unit wiring harness, all colors should match up, if something does not match (say a red hooked to a black – very bad) you probably did it wrong and will blow a fuse………..or worse. So make sure they all match and you will be good to rock! Wire up everything THEN plug it into the car, that way you are not wiring up live wires and NEVER cut the car harness……NEVER.
Any more questions hit me up anytime. Here are a few pics to help out
THANKS FOR THE HELP. MY QUESTION IS THIS..WILL THE CENTER IMAGING AMP AND SPEAKERS STILL BE USED? I HAVE NOT HEARD ANYONE MENTION ANYTHING ABOUT THIS AMP AND SPEAKERS. APPARENTLY, THE 4 SPEAKERS WILL WIRE DIRECTLY TO THE HEAD UNIT AND THE SUB AMP TO THE HEADUNIT, WHAT ABOUT THE OTHERS? ALSO, COULD YOU PLEASE GIVE ME PART NUMBERS TO THE WIRING HARNESS KIT AND TELL ME WHERE I CAN PURCHASE IT ONLINE? I CALLED AROUND HERE TODAY AND APPARENTLY I LIVE AROUND A BUNCH OF PEOPLE THAT DON'T KNOW ANYTHING ABOUT THE HARNESSES. THEY TOLD ME TO TAKE MY OLD RADIO OUT AND BRING IT IN AND THEY WOULD TRY TO MATCH IT UP.. I AIN'T KOOL WITH THAT AT ALL. IF YOU COULD GET ME THE NUMBERS OR SEND ME A LINK FROM SOMEWHERE ONLINE, I COULD ORDER IT RIGHT AWAY. THANKS ALOT FOR YOUR HELP. JOHN
