BUT, a instrument panel with a tachometer for a V6 is different then a V8.
It can be converted by change Capacitor C103.
Capacitor C103 with a V6 has a value of .0033uf (3300 pf)
Capacitor C103 with a V8 has a value of .002475uf (2475pf)
That sound good but my truck is a 91
I'm bout ready to replace the broken up plastic with the good 94 dash and wire it up with the 91 stuff and not look back..
