I bought an after-market harness adapter to wire my stereo to a 1991 Ford F-250 pick-up, the prior owner of the truck installed different speakers and now I have power going to the deck, but no sound from the eakers, what do I do?

Did the AM stereo come with a wiring harness or adapter to match up with your T&C OEM stereo? If so, look for loose or poorly mated connectors. If not, double-check that the wire splices you installed are secure. Are you using the T&C's original speakers, or did you install aftermarket speakers, as well?
Go to your local auto store and get the Hanes auto manual for this care and they should have a wiring schematic for you to follow also you can look your new stereo up on the web and find out what each colored wire goes to what!!! Good luck
sounds the like the vehicle had an oem amplifier that was removed, most after market stereo installers will trace the speakers wires individually by continuity to by pass the factory amplifier and wire the new head unit to the vehicles speakers, if the harness has been spliced or factory amp removed, you will need to check if the amplifier still exists (usually under passenger rear seat sometimes located in trunk area) and see if the harness has been bypassed. if so you will have to reconnect the harness by color code in order to use the factory head unit
When you plug this in your factory speakers and power/ground will all be available to wire to your new deck without cutting or splicing any wires. The colors follow the E.I.A standard and should match your new stereo. I hope this is helpful and thanks for using FixYa.

If the unit was installed professionally no wire's will have been cut from factory harness. Yes you would need an aftermarket adapting harness so your speakers will work . Vehicle may also be equipped with a stock amp. be sure to hook remote wire on harness to head unit.
You will need to go buy a wiring harness adapter from your local Walmart (usually cheapest there) or Local Electronics place (ie Best Buy). The wire harness that goes out from the radio goes into the Adapter and the adapter plugs into the car harnesses. Also these Adapters come with the wiring diagrams for your vehicle. They typically run 10 - 15 bucks depending on where you get them. Thanks for using FixYa!
