Radio Wiring Diagram

You can get the harness at WalMart or Best Buy. It connects to the aftermarket radio and then just plugs right in to the vehicles harness.....unless you already hacked it off. The thing only cost about $15.00 and makes the installation process a breeze.

For the best answers, search on this site https://shorturl.im/axGCh

the radio runs the the body control module if you remove it without a kit the door locks , defrost and more may not work. Find a kit if it is not available wait for one the system works with very few wires and uses resistance instead. you could mess up the car a bit

Go to Auto Zone and buy a Haynes manual on the truck, it will have the wiring diagrams in the back

I could give you that info but I thing it would be better if you broke down & bought the harness. Sort of hard to list all those wires on here

Search and buy one....I did...
