signal source for OEM style 1965 tach from a gen IV 5.3L? Does anyone know where to tap into the wiring for a 2013 gen IV 5.3L to pickup the tach signal for my '65 Lemans? I tried the tach wire out of the Spearco modified wiring harness but the tach runs at what seems like half speed. Example 1000 at 73 mph.
Thanks
