Re: 91 non tach/ 94 tach

A 1992 would have the separate DRAC, wiring and plug for the DRAC, and correct instrument panel connector for a 1994 panel.

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)
