Hi All
After quite a bit of time I figured out the can commands to enable a dodge/jeep EHPS. (charger/Challenger/Cherokee etc)
message if you need info, code/ schematics

Hi All

Still a work in progress but using a atmega328 mcp2551 mcp2515 and a handful of passive
Basically connect the 2 main power wires connect the can controller to the can transceiver
Connect the center wire on the pump to 12v+ can_h and can_l
Send 0x308 0x54 0x01 0x40 0x00 0x00 0x00 0x00 0x00 and the pump will start. I believe it's running at about 80%
Still looking for the commands to control the speed.. if anyone has a 2011-15 dodge or jeep with the EPS if you could log the can data at highway speeds for a few seconds probably can solve that and make it controllable with vehicle speed
I'll try to follow up with schematics and arduino code if anyone is interested.

will do remy, I'll put together some better documentation

Nicely done.

Suggest you start a thread and put everything in one place vs burying it in the clutter of this thread.
