looking for an accurate wiring diagram to put my pioneer stereo in my truck. its a 92 f350 crew cab diesel

 

The easiest way to do this is get an adapter harness from the car parts store. See if they carry one for your model. It plugs right into the factory harness without cutting it up, and then has pigtails that you use to splice into the new aftermarket radio.

 

now that would be nice if the wife ever gave me any money but i get to make due with what i have plus as sad as it is and i do hate cutting in to any vehicle, ive already cut the old factory plug off.

 

See if this matches up.

if you need a circuit diagram send me a PM with a real email address and I'll send you a PDF of it all.
