I read on here that the standard radio harness will work for an aftermarket HU insall, but will you retain sound out of all 7 speakers. Someone said there is a blue wire that needs to be connected, but to what? Im looking to buy and install this myself, but would like to retain the factory amp and all 7 speakers. Any help is appreciated. Thanks

 

blue wire is the amp turn on wire, should be able go get a wire harness that will more or less colour match everything

 

can i jump the amp turn on wire to a power antenna wire from the aftermarket head unit, and avoid buying the amp integration harness and rol with the standard stereo installation harness available just about anywhere?

 

Hook your amp wire up to the accessory wire, easiest would be to splice into the cigarette lighter beside the cup holder.

 

Thanks for the help.
