To use the diagram you originally posted.
The two connectors shown are the connectors for the ignition switch.
unplug the connector, you will be testing the ignition switch side of the plug (not the body harness side)
With an ohm meter, probe the two terminals shown in the diagram.
For instance, to test the acc mode, put the leads on terminal 3 and 4. you should get a low reading (like you do with the two test leads touching each other). Any reading indicates continuity. So in acc mode you should have continuity between 3&4 but no other terminals.

In "ON" 2,3,4 should have continuity with each other, and 7&8 should have continuity with each other, but the two sets do not have continuity between them, and so on.

so the switch works fine, im also checking fuses
20ADOME- ( is the culprit, making my clock, radio and cig on)
tried pulling gauge-(good, dosent work when i pulled it out)
radio-(i pulled the fuse and it still works)
cig-(pulled the fuse, the cig light still works)

any suggestions?\
i tried taking apart my column, covers, center bezel, couldent find any wires touching or frayed.
unless i change my cylinder barrel (not switch)
