sup guys,

Im in the process of putting in my new 07 auto ecu to my 04 manual and when i connect the 07 ecu it won’t communicate to the scanner which is genuine dealership hds. i’ve done the whole can bus wiring. with rewiring the obd port and connecting the can pus wires to the green box.

any ideas?

Double check the wiring as it sounds like it has not been done correctly. Try swapping CANL and CANH.
