Default What's the verdict on BS3 tach output and OBD-1 clusters?

Gonna try to get by with my OBD-1 cluster for now on my tach. Do I need an interface or wire it straight in? Manual says 4 pulse per rev.

Bump. Factory is 40 pulses? I would need a box for this, no?

My buddy has an Autometer 5" tach and he said he wired it right to the factory signal wire for his LT1.
