Hello, I'm in the process of wiring up a Toyota GR supra headlights and noticed that these are Power and ground but controlled via Can Bus.

This car will be running on a ECU masters PMU. From what I gather Ecu master will be able to do custom messages to control the head lights via CAN, whats your take on this?

thank you.

Hey Johan,

Yes, the ECU Master PMU can do custom CAN messaging which is very handy! But you will need the reverse engineer the CAN of the GR Supra to find what messages to send to the headlights to turn them ON and OFF.

I have no experience with these cars so I can't help more than that, sorry!
