I bought a Sunpro II tach for my 1995 3.1L V6 Century Special. (It only has 30000 miles on it, so im hooking it up I tried to wire it, but cant seem to find the correct Tach signal. or any signal for that matter. The green wire on the tach goes to the signal wire, so if anyone knows where the wire is, that'd be great. Also, i cant seem to find any wire that i can hook up the cluster dimmer to (which is the white wire on the tach). any help would be nice.
