<VV> JET SIZE and non corvair question

[N2VZD at aol.com]

i have 3 vehicles running powerglides , dual exhausts on 140 manifolds and  
3:55 differentials.  they all have 51 jets in them at the moment.   they 
seem ok , but the one with the OT10 cam might like a step larger.
i run high test , and electronic ignitions..not pertronics.
my non corvair question: i need wiring diagram to power up a 70 caddy power 
 antenna. can anyone help me?web address or a scan, or even which color 
wire goes  where.
regards, tim colson
