I am trying to install the Speed Input and Gear Positon harnesses to my 07 10R. I already have a GiPRO installed. The instructions say that I need to find the signal wire of the speed sensor for the Speed Input harness. The BL/Y wire of the sensor is hooked to the W wire of the GiPRO and the BK/Y is hooked to the BK wire on the GiPRO. For the Gear Position harness the BK wire is hooked to the BK wire on the GiPRO and the G/R wire is hooked to the G GiPRO wire. Can anyone tell me which of these wires are the signal wires. Thanks in advance for the help.
