I'm curious if an old EEC-V box such as my JZP3 or EQE3 units have a CAN bus on the pinout. I have a CAN capable microcontroller with a few PWM outputs I am hoping to interface with an EEC-V so I can poll the ECT sensor and control a Meziere water pump and e-fan, ditching the mechanical thermostat entirely.

It looks like the older boxes only have an SCP datalink interface, not sure if that's something I can tap into or not simply based on not understanding what the protocol entails. If anyone has any additional information on that they don't mind sharing, I could possibly entertain that option.

My last resort would be then to use an ADC on either some existing thermistors installed on the engine to provide analog gauge signals or a new sensor of my choosing. That would almost certainly require the use of another board mainly due to the need for a different voltage divider than is available on my CAN/PWM board.

i believe any canbus functionality would be in stock fords with canbus like 2003+ but that doesnt cover what you want probably. even GMs allante had some strange canbus not quite the kind we think of today

AST1 has it and that’s about it as far as i know
