so i just got a 87 camaro iroc but its still got the hurting stock system.... so im looking to intstall a new head until but i don't really know how. on my firebird i had a buddy install the deck for me and we didnt have a wiring harness so he just hard wired the whole system up and i really don't know how to do that. i heard its wicked easy with a wiring harness but i don't really understand how they work. if someone could just decribe the easiest way to install one that would be great. sorry if this has already been posted but im pretty dumb obviously so bare with me

 

easiest way involves a wiring adapter and a mounting kit

mounting kit allows a standard, single-DIN size radio to fit the gm DIN+1/2 opening.
wiring adapter has a plug that snaps into place with your factory wiring and bare wires on the other end. these bare wires are soldered/heat shrinked or crimped (do NOT just twist and tape. bad bad bad for a car environment) to the bare ends of the new radio's harness.

all wires are color coded and the instruction manuals with both the radio and wiring adapter will have a pin out of their harness connections.

 

The best part about the adapter harness, besides the fact that it keeps your car intact, is that it lets you do all of your connections on a work bench instead of buried inside of a hole in the dash board.

Here's a write-up that I did a few years ago (scratch that... over 10 years ago now!!) that might help:

thanks for the help guys it should be pretty easy once i get the right stuff.

 

You're one of the lucky ones to have the car's wiring harness intact. To install a stock deck in my 89, I had to get the harness for the radio and connect that to the cut harness in the radio hole

 

yep u can get the wiring harness connection and adaptor plate from good old walmart both for under 30$ total.. should only take maybe 30 min to install just match the wire colors together and plug it in
