I am trying to find out the pinout for a Ford cassette/radio - the label says "E9DF-19B132-AA" (there is an "88-" in a box tot he far left on the label).
The connector says "E6DF-14A459-C" -- it is a rectangular plastic block on the right-rear of the radio, with 15 flat pins -- 7 pins on the side facing the middle of the radio, and 8 pins on the side by the edge of the radio.
I've spent the morning goggling my fingers out, and there just ain't much that I've been able to find out. As best as I can tell, from what scant info I've turned up, this is a somewhat older unit (early '90s at best), and has "common ground" speaker connections. I've found diagrams for a newer unit, with a similar connector, but with two sets of 8 pins, and the wiring is clearly NOT compatible with this one (i.e., the pin in the position that's empty on this radio is NOT a "n.c." pin on the 8/8 type radios).
I popped the two lids on the radio and looked at the PCB. There are some silkscreened bits by the ribbon that runs to the connector block. I am pretty sure I can make out the four speaker lines, and the antenna motor line, but that's about it.
I guess I could spend some time with a VOM and trace the main power line (from the power switch, which *seems* to be a traditional (mechanical rather than "soft-touch") switch, and I could probably manage the same with the display lamp, but that'd still leave me without any power going to the memory line, which wouldn't be real good.
This was a two-dollar special at the Goodwill, which I plan on making into a "redneck boombox" (something with fairly decent sound that I can haul out to the barn and the field, fairly cheap, rugged, and with decent enough sound for that environment).
Does anyone know the pinouts for those two connectors (the 7 pin and the 8 pin)?
If all else fails, does anyone know if the world will end if I *bypass* the connector? I can see that there is a small PCB under the pins, with some components soldered to it -- unless I desolder the 15 pins and removed the littlel PCB I won't know what's going on there. I am guessing that it's probably something to allow them to use the same radio with different vehicles, or, perhaps with different feature sets (i.e., rigged to shut down the internal power amps to use with an external booster amp), by putting a different plug-block on the radio when they build it.
(I read that some of the newer radios have jumpers that accomplish that kind of thing, I don't know if any of it is a factor with this older job. I *do* know that it's got two power-amp IC-modules on a heat sink, so I presume it *should* be able to drive a pair of speakers.)
Sorry if I am coming off like a complete nimrod here. :) I'm a former camera repair tech, so I can sling a soldering pencil and so forth. I've been out of that trade for some time now, I'm halfway through disability, health is shot, can't do fine work anymore, but something like this wouldn't be much of a challenge presuming I can know which pins are which. I really don't want to do a bunch of work on it, and then let all the smoke out the first time I turn it on.
I know it's not much of a radio, but for my purposes it'll be OK, if I can get it working.
Thanks in advance for any suggestions/ideas.
