1984 Pontiac Firebird steering column wiring

Electrical problem
1984 Pontiac Firebird

I am installing a gm column in my wifes vw dune buggy
i need to know which wires are which on the connection that is on the column. I will attempt to use the factory wiper control and the ignition as well as the horn. I am unsure if it has a delay or not on the wipers if I can get it hooked up for low and high I am okay with that.
