Just throwing this out there to see what input you all have. I have been fighting the dreaded tape deck parasitic drain on one of my SHO's. I have totally removed the drive from the ICP (the football radio), but it still wants to heat up the huge heat sync by adding an additional 0.5 amp draw when everything is off. This naturally causes random issues of a drained battery. My temporary fix is going to be to wire the power to the radio to only be on during run. This is necessary as many of you know, the EATC is managed by the ICP. With no power you get defrost/foot and heat, not to mention the A/C cycling when the car is turned on. This is unacceptable, thus the reason for the temporary fix. Having said that, at least with this SHO, aptly named "SHO Foo", I want to keep things stock looking and operational where possible. With very few of these radios around in working order, I happened to start researching some replacement ideas. So far this is what I have come up with: 1) Replace the who system with some aftermarket system and controls. 2) Create an aftermarket design that works with the stock system using the stock ICP and controls the system with the stock ACP commands. #1 Is doable, but likely looses the stock ICP. And requires a lot of rewiring all connected systems. Nothing appears to exist to make this venture simple plug-n-play. Though it cound be done with my flavor of Arduino or even Rasberry PI. #2 Seems the best course of action. Allows for stock controls to be used with my flavor of tinker board, likely Arduino, interfacing with the original system and modernizing it. Challenge with #2 is getting the Ford ACP commands. I found a link on Instuctables where someone interfaced with the ACP to act as the CD changer. There is a glimmer of hope with that concept, as the basic command structure is made available in Arduino code. The part that is missing is now is just finding the commands needed to communicate with the RCC. Since the ACP is just a serial communications, no encryption, it would not be trivial to rig up a connection to a port on a computer and attempt to detect the communications when pressing the various buttons. If I can get this off the ground I expect to integrate blutooth communications from my portable device for sound. I'll upload the links I have to the Ford ACP commands and Arduino projects for anyone interested in this venture.
