Killing Dist pickups ?

Bought 2 new LX102 pickups and installed 1 .
Still no signal to box .
While messing with this I created a short somewhere and fried the wires to the ballast.
I unwrapped the harness under hood and am tracing my short.
Last week I was sorting out all my lighting and that involved the turn signal switch . Got all the lights (signals, flashers , breaks etc.. )but no horn . So I am at the point of checking for grounds at the T signal connector and find every other pin grounds out. Is this normal ?
FSM has no schematic for the switch itself and I am finding many differing versions online.

BTW, why is there a Ground terminal on the ignition switch but no wire to it ?
