There was NO room for the standard 10-pin tether board in the Williams K4, the clearance is VERY tight and the floor of the cab is right there. I ended up using the Hirose DF3 10-pin mating connector and epoxying it in the gap. Obviously, I had to move the wires from the harness connector to the new connector. Since there was no room for the PV diodes, they're skywired to the motor and the purple wires connect to the other end.
Ignore the missing motor, after I was all done with the upgrade, I found out the motor was bad! It has a short to the case, and needless to say, this really annoyed the PS/3 electronics! I'm waiting on the new motor to wrap this one up.
Dennis Holler posted:John, Did you ever find a solution to adding whistle smoke, rather how to control it? I think there is room for that feature in the Williams K4.
Well, the old ERR Sound Converter was a perfect board to tap off the whistle logic, but that died with the old ERR. I am planning on someday building a small board that will tap into the serial data and just drive a whistle smoke unit, it's somewhere in the planning.
