I am planning on installing an EVO-ALL with T-harness on a 2016 Mazda CX-5. This is my first time doing this, I was looking over everthing on WireColor as well as guide 62941. I think I am able to find everything I need except WireColor does not show a wire to connect A8 to (ground while running). Does this wire just get grounded to the vehicle or does it need to go to another wire?
Also, WireColor states that wire A2 going to Lock needs an in-line 1k ohm resistor. Is this necessary? Lock & Arm is also called out but guide 62941 does not show a wire going here, does anything need to be done for Lock & Arm?
