What wattage 120 ohm resistor should be used to terminate the CAN Hi/Low signal coming off the ECU?

Does not matter. 1/16W will work.

Ok, thank you.
Also, this may sound like a stupid question, but should I be reading 120 ohms at the end of the CAN wires, after 1 resistor has been installed on the ECU side of the line, when measuring resistance between CAN Hi and CAN Low? I thought both ends needed to be terminated in order for the CAN network to see 120 ohms of resistance?

If both ends are terminated then you'd see 60 ohms resistance. The termination is not that critical - the bus will work as long as there is one termination, but of course there should be two.

Alright
Is there any way to contact you guys via phone or video call to discuss an issue I'm having with my CAN gauge. The gauge manufacturer is certain it is an ECU problem after we have performed various tests to type out the gauge...for what that's worth. I'm sure they all say that. But the information I need to present to you is very indepth and I'm sure I could answer any questions you may have more promptly if I actually spoke to someone.

Our obligation extends as far as verifying the CAN output of the KPro meets the specifications. We can do that if you would like. I do not think there is anything that will be solved over the phone.

Ok, let do that then. How would I verify that the CAN signal is to specifications?
