Car in question is a 1991 GT with Premium Sound system.

The head unit crapped out and I need to swap it out. I have another aftermarket head unit that I wish to install, but I'm clueless on how to wire it in.

Here's a few pics I took of my setup and the head unit that I want to install.

BTW, I tried some of the pre-fabbed wiring harnesses from a local parts store (looked up in the Chart) and the wiring was NOT right. I figure since this is the Premium system (for 91) with the EQ/AMP, the wiring HAS to be different some how.

How do I go about figuring this wiring stuff out ????

I'd appreciate any advice!

It's super easy to run wires into the doors of a fox body. I'd tap the factory harness for power and run new speaker wires. (that's what I do in all of my Mustangs) It's simple, easy, and better for the system. (upgrading the puny factory wiring)

If you have more specific questions, let me know!

I wouldn't.....

Newer headunits are LIGHT YEARS ahead of that EQ.....most have built in EQ's and those that don't are still better. JMO.

yep. What he said. Bypass as much of the factory stuff as possible!

I think I'll go ahead and just do that. Only problem is the EQ/AMP bracket is RIVETED to the radio. I don't want a big hole beneath my new radio, and I think I'll keep the EQ/AMP there to plug up the hole.

Guess I'll just drill out the rivets. :confused:

Any other ideas on how to do this better ??? :confused:

just buy a mounting kit! Probably ten to fifteen bucks at your local circuit city or best buy?
