in the pic the blue wire is Accessory Switched 12v+ Wire: Blue
and on the radio the red wire says acc.
the blue wire is about 2 times the size as the red.
do they go together.

also what should i do with the black and yellow dimmer whire. there is no place for it on my new radio?

if the blue one is from your stock harness then yes that's the +12v accessory wire. the red one should be +12v power to the radio.
