Progress continues...but I have one question - which side of the transmission provides the supply to the cooler in the radiator? It seems like it's the drivers side, but I can't find a definitive answer.
Got the board wired up as far as I can go without the thermocouple amplifier module. Also got the relay box mounted in the car and mocked up ready to start doing the chassis-side wiring. The boost sensor and the vacuum sensor are also mounted and ready to go.
I also tackled the piece of the project to include a vertical card compass and got the compass working with simulated data. The compass module will be here in about a week. Unfortunately I don't think there will be room inside the box... of course it probably doesn't make any sense to have the sensor module in the box anyway due to interference.
