So I did get my Raptor shift light. however, while installing there is coming in some issue yet : as I did install before Whites performance coils, and there is Raptors warning not to connect the leads to the coils, there is coming in some issue...

I need to know the vehicles output speedsignal lead from the ECU and second, I need to know the tach output lead.
The electric part of the manual indicates 2 leads (blue and red one )leading from the ECU to the tacho and speedometer.
Now the big question : which leadcolor is the output one
