<VV> wiring harness

[sharpiebandit06 at bellsouth.net]

Hey Ya'll,
   I have a question concerning my wiring harness. I have a 65 monza coupe 95 hp. I got a corsa dash and i was curious if I could hook that up directly to the main harness and then purchase a corsa engine wiring harness to supply the tach and thermiester wiring needed for the dash and extra gauges. The big question is: can I hook up corsa engine and dash harnesses to the main harness of a non-corsa corvair and they will communicate? also, I have back-up lights, brake lights, and turn indicators, but no tail lights when I turn them on at night, does anyone have a clue what the problem is?
