Where to tap speed sensor signal?

[SportsterDoc]

Unconfirmed or speculation, pick whichever word you want.

I've already had this conversation over PM and it was followed with the caveat of "don't blame us if you smoke your ECU".

I'm cool with that warning- and therefore sit back and wait for confirmation from people more knowledgeable about electronics and testing to let me know.

I on the other hand will be the guinea pig on the cost, labor and risk of having to pretty much replace my entire engine on possible failure of my 'performance' camshafts.

Take a look at your schematic. The speed sensor + is pink/green.

The differences between non ABS and ABS schematics have been sorted, but
the Signal Dynamics website (link previously supplied) advises to connect their white wire to the speed sensor.
