Electrical help
I would start by going directly to the ignition switch connector coming out of the column. ID the ACC wire and check that it is powered up with key in either "run" or "ACC" on BOTH sides of the connector
You need to get yourself a factory manual
NOTE "start" is shown somewhat incorrectly. The Yellow and BRown are NOT interconnected. They are separate switch contacts for isolation
S2-12 Yellow is "start"
Q2-12 BlacK is your accessory feed going TO THE MAIN ACC BUSS in the fuse panel
J2A-12 Dark BLue is your IGN1 "run" ignition power
J3-12 BRown is the IGN2 "bypass" circuit to coil
J1-12 Red is the main power coming in from the ammeter welded splice
E2-20 Orange is dimmer controlled dash lighting either to shifter quadrant or "key in" light don't remember
M16A-20BlacK is the horn switch wire
