i have a 79 f250 std cab but there is no factory wiring for a radio the cutout is there and it is din sized already but i would like to put some music in there so i would need to run door speakers run the radio wires add power etc. and probly add rear speakers somehow. if not then just fronts

how would i do this????

 

well u need to get some supplies and tools 1st
-10 foot roll of 12 or 14 ga. primary wire- red
-10 foot roll of 12 or 14 ga. primary wire- yellow
-10 foot roll of 12 or 14 ga. primary wire- black
-20 foot roll of 16 ga. speaker wire
-30 feet of 1/4" or 3/8" wire loom
-small package of plastic zip ties
-small package of assorted wire connectors

tools
-wire cutters
-crimpers
-test lite(12volt) or multi meter

now start at your fuse panel, using test lite, locate an
empty slot for 12volt + constant, and locate a empty
slot for 12volt + acc(or on with key)--then disconnect BAT

next size up your blk, red, yellow primary wires to run from
the radio opening to fuse block--with some slack.
put these wire in the wire loom, install in truck , tie it up
out of the way with the zip ties,

now connect your black wire to a metal ground, connect your
yellow wire to the constant 12volt + in the fuse block, and connect
your red to the acc (on with key)12 volt + slot in the fuse block.

now at the radio opening , connect your newly run wires to the wire harness
supplies with your aftermarket radio. the wire colors should match up--but check the
radios manual to be certain.

run your speaker wires much the same, size them up with some slack, wire loom them,
install in truck , tie up out of the way - with zip ties. make your connections
