I purchased a stock am/fm/cassette/CD to replace my stock am/fm. The power plug is the same but not the speaker plug. In fact, the CD unit has three smaller plugs. Both units are for a 1995. My other truck that has am/fm/cassette has the same plugs as just the am/fm. My Ford service manuals dont have schematics for any radios that I can find. The am/fm/cassette plug has 8 wires and I assume that covers the four speakers. Anybody have any schematics AND/OR speaker plugs for a CD unit?

Thanks Ron Stauffer

 

The wiring plugs should be the same... I've never seen one any different from another one.

 

Maybe the CD is a premium sound system and requires an amplifier.

Here's the connectors I found that plug into the radio.

 

Here's more:

 

Here's the schematics: The first one is regular, the second is premium

 

Wow, As usual, very good post Cuda. I traied to rep you but you know.

 

Thanks very much for the info Cuda Jim. It is a premium sound setup, so it has an external amp? Know if it would work without the amp? Anyone have the plug ends, amp if necessary?

Thanks Again

The best way to do an aftermarket radio with a stock amp is to bypass the whole amp. Crutchfield has a nice harness that will plug into the output plug of the stock amp to go out directly to the speakers. Of course now i can't find the harness. I used one on my old truck to run from my amps behind the seat back up front so I didn't have cut the factory wiring. The whole harness was $30 or so but it was 8 wires about 20 foot long so you could use it in the rear of vehicle for amps then run it up front to the plug under the dash at the stock amp.

 

Tim, he's trying to go from a stock AM/FM to a stock AM/FM/CD as I understand it... the harnesses should plug right in, I can't figure out why they would be different.

 

Yes that is right, I am going from a stock am/fm to stock CD. By the schematics it is a premium sound. The power plug works, but the speaker hookup is totally different. If there is an external amp with the premium, I didnt get it. So what is the best route to go now?

Thanks Ron

 

Oh I see. Sorry. The best route will be just get an after market stereo with CD player then. Or you will need to get an after market amp to power the speakers from the factory radio. which will also be difficult without the factory connector.

 

Ron, you might try going to a Walmart and picking up a wiring harness adapter that is used to adapt an aftermarket stereo to the stock wiring. The adapter I have has 2 separate harnesses (one power and such and one for speakers) and both harnesses have two different plugs on them... maybe you could use the other plug on the aftermarket adapter to tie things together?

 

The problem is that the premium Ford cd player has outputs that are similar to preouts on an after market stereo. Though they are not RCA connectors. So the radio doesn't have enough power to drive speakers without some sort of amp.

 

I have a pic of the back of the unit. It is a jpeg file. Since I havent done much posting here and never a pic, I am unsure how to do it. Super Duty you could then see what I have to work with

I've never dealt with a truck with premium sound before. Ron if you have photobucket or webshots you can post the photo real easy, if not let me know and I'll shoot you my email addy. Tim's advice is probably more sound than mine though!
