Anyone who's more engine-aware than I want to hazard a guess as to where on the Radical I can tap into the brake lights and tach? I'm wondering if maybe there is a happy spot behind the dash I could use. I'm going to hook up the Traqdata this weekend so I can start showing tach and real brake on my videos, the manual says any 6 to 12v brake light is fine for brake, and I can do that easy enough by tapping the light cable in the back, but tach they want one pulse per engine revolution so I need to find a tach output behind the dash or an actual output for reading this off the ignition box which I also don't know where to find.

I'm guessing I can at least get 12v power behind the dash so I can tie into the emergency off? Speaking of my emergency off, prior to Barber, it used to turn everything off, now it no longer seems to have that effect on some things such as the water and fuel pumps, I have to turn those off with the right-most switches on the dash now.

To deviate a bit on the thread, I'm wondering if these would plug into the Radical sockets, I've been wanting a real in your face brake light for mine since I'm doing mostly track days that will have drivers behind me that require three times the distance to brake:

Would this do? Should get their attention pretty quickly?

Not if the person behind you is dumb and is waiting for you to brake first. :)
