Can't get my stereo to work. UPDATE - It works!

I'm having issues with my stereo install. I removed the factory (as far as I can tell) NON-premium radio. There's no equalizer so I assume it's just the standard AM/FM tape player. Not sure if there's an amp or not. I'm replacing it with a Pioneer DEH-1700 that came in my parts car.

I used one of those wiring adapters that I picked up at Kragens. I double checked the wiring with my EVTM. I'm sure I've got the speakers wired correctly (BTW, aftermarket speakers that were already installed in the '86). I wired the red to red (power), black to black (ground I think) and yellow to orange (illumination). I've got power. All lights come on and all controls work (digital). But, I've got no sound at all! The system in the '86 worked fine before I pulled the radio. And, the receiver worked fine when I pulled it from the parts car. The only thing is, the receiver connector and harness were out in the elements for a couple of months but I soaked the connector liberally with contact cleaner and I don't see any corrosion on the prongs.

Anyone have any ideas? Help!

evintho, I've done installs like that before and thought, "What the heck? The old one worked, why doesn't the new one?" So, then I've pulled the new unit out, reinstalled the original and verified it still worked. If the old one does still work, then it shouldn't be too difficult to retry the new one. If the old one doesn't work anymore, then you've got to troubleshoot that one. In that case, I would use one or two standalone speakers before connecting the car speakers again. It's much easier to figure out what's going on when the speakers are sitting right in front of you, just in case you bumped something in the car wiring. Good luck!

Just ran across this. I have premium sound without an equalizer. I hooked up to the factory speaker wiring. Looks like I just fried my head unit!!

Evintho, I resently did a install, what are you plugging your aftermarket stereo into? Do not use the original harness that the factory radio was plugged into, drop your glove box and there is another harness there, you need to use that harness, if your speakers are connected to the factory radio harness they will not work, also you need to disconnect the amp thats in the trunk behind the rear seat, also the harness you need to use is up against the dash to the left of the glove box door right along the top edge where the glove box closes, my install did not have any sound until I found this plug, you need it to make it work, unless you feel like re-wiring everything which would not be fun, I hope this helps and if you have any questions let me know.........Rod....oh yeah mine is also an 86TC

Rod, thanks! I'm heading out in a few minutes to give it another shot. I'll disconnect the amp and search for that secondary harness. Hopefully I didn't destroy the head unit!

Hey, I am doing the samething.The only thing is that there is an aftermarket Panasonic CD player already installed but the rear speakers are run by a aftermarket amplifier.All the speakers are Ford stock units.I just don't know why they ran the rears off an amp.Does this 87 TC of mine have the connector that you talk about in your 86's???I read the FAQ on aftermarket deck install.They guy before me just cut the factory connectors off and wired everything in.kind of a hack job.

Found the secondary harness exactly where Machzman said it would be! It was wrapped up in some sort of rubber covering. I now have tunes! Thanks everyone for the input! For those who are about to do it, here's the procedure.

Firstly, refer to the foxthundercats website in my second post in this thread to determine exactly what type of system you have.
My '86 TC had premium sound without an equalizer and I was installing an aftermarket head unit only.

1) Disconnect negative battery cable and remove original radio.
2) Open the trunk and remove trunk liners, cardboard cover and disconnect the 2 connectors for the factory amplifier, which is mounted behind the rear seat.
3) Remove glovebox at the piano hinge.
4) Locate secondary radio wiring harness which is stuffed up against the dash to the left of the glove box door right along the top edge where the glove box closes.
5) There are 2 connectors. Leave the grey one connected and pull the black one out for access.
6) Obtain a wiring harness adapter from WalMart, Kragen, Autozone, etc. Runs anywhere from $10-$20.
7) Splice the aftermarket head unit harness into the harness adapter you just bought.
8) The harness adapter will have 2 connectors. The black one is for speaker wiring. Plug that one into the black connector you found above the glovebox door. Plug the grey connector into the other grey connector directly behind the factory radio. Plug in your aftermarket connector to the back of the head unit. Don't forget to connect your antenna lead.
9) Reconnect the negative battery cable and turn the unit on to test and make sure you have power and sound. If all is well, button everything back up and enjoy your new stereo!

Hey Shane, I think its the same as the 86TC, just do the procedure that Evintho explained, except maybe unplug the aftermarket amp for now so nothing happens to it.I also run an aftermarket amp but it is only to power my 2 12" subs, I also have all aftermarket speakers (6) Kickers and it sounds awesome, my headunit is a media player so I am putting in a playstation right now, and when track time comes the Subs come out.... Hope it all works out for you............Rod
