1970 Ignition Switch T/T

by Pete Z
(Houston, Texas)

1970 Corvette 454 4-speed
Tilt Telescopic A/C
I just completed changing wires under my hood and now under my dash with NEW Wiring harness. Prior to changing out the Dash portion my headlights and wiper door and wiper motor worked (with the new wiring harnesses under hood). Once I installed the new under dash harness - only my headlamps work.
The wiper motor is not working, neither is the vacuum door.
I checked for voltage to the cutoff switch under the dash in between the two vacuum over-rides. It is not receiving voltage. Fuse is good, reconfirmed with meter.
Car is also difficult to start, did not appear to be a problem before
Any suggestions
Do you have a photo of correct placement of connectors into the Ignition Switch
How do you adjust Ignition Switch
