Yes it can. Guides are not available yet though.


The difference is CHR7 has some extra connectors for the CAN-BUS.

If using the OBD plug, cut out the ORANGE CAN2 wires.

You can also use the 2 pin gateway harness to connect CAN at the gateway like on the 2018 model.

Great. Just one more thing. The red connector on the t harness only have the two data wires connected. When I look at the manual installation,there is two other wire for run signal. Just wondering if I will have to make those two run signal connections. Thanks for all your help.
Will work without those extra wires
