Tach Wire 2000 ST2

[666r]

I am trying to put a aftermarket tach on a 2000 ducati ST2  The wiring harness was modified by someone other than me can anyone tell me what color is the tach wire for this bike.
Thanks Ricky

If it has one (it may not) it'd probably be the "J" input on the round connector that goes to the instrument cluster.

At least that's what's used on the 2001 900/750
