That makes sense. I may not use the grey wire at this point. Thats a good idea taking orange wire to the brake light switch. I really didn't want to drill a hole in the brake pedal and I haven't added a trans brake yet so I was still considering best option to hook it up.For mine the grey goes into my manual rev limiter control.
I took the orange to the switch on my brake pedal. Then the grey to my potentiometer on the cluster.
That way I can turn the potentiometer & set the RPM’s to the RPM’s I want the TR6 to limit.
