Here 4 Blue Can1 Can2 wiring

[xfacta (Shawn)]

This is what I’ve found:

@xfacta

All of the Here4’s I’ve seen so far, the CAN1 connector is the one with wires green, white, blue, grey, and should be used for performing the update

After the update the CAN2 port (red, orange, brown, black) will NOT work.

Same as other sources
