Note: An Volt 6 & 11 (A33 & B24) have Pullup resistors on them and so can't be used for typical An Volt
purposes.
Note: Ignition 8 (C19) has a pullup resistor and so can't be used for typical Ignition purposes.
Note: Injector outputs 5-8 are on one of the expansion headers and so can be used for Sequential Staged
Injection.
Note: AC Request comes in on CAN DI 5 (instead of DI 7) in 2012+ models.
Note: Aux 16 (Rear O2 Heater) is Low to disable heater and floating to enable heater.
