So Joe and I had hit up a U-Pull in Houston, and in pulling parts out of a '91 Comanche, for his '88 Pioneer, it had a Sparkomatic AM/FM/CASS unit, so I decided to snag it. It's an SR350 model, a four speaker unit with balance and fade, and digital tuning, display and clock. PROBLEM: Sparkomatic never put a basic wiring diagram on the case, and other than switched & unswitched power and speaker return, so I get to play "hook up wire, test which circuit it is." The speaker wire colors for this are grey, green, blue and white, so, we'll see how it goes, or even if the bugger works. If it does, Babe'll be back in business!
