Wiring... Plz help

Just take each circuit separately. We can step you through it. Example, The TS switch is not that hard, you have the following terminals:

INTO the the column TS switch, you have TS flasher and hazard flasher, as well as switched brake light power..

None of that does anything until activated. If the switch is centered, the brake light power is routed through and out the switch to both rear TS bulbs

OUT of the switch is left and right front turn, and left and right rear turn. The front turn wiring branches off to feed the cluster turn sig indicator lamps

Ignition switch: Again, just separate what is what. You have main battery going IN

Coming out you have IGN1 which is hot only in run, and IGN2 which is only hot in start

You have the start trigger going to the start relay,

and you have the accessory output which feeds down to the accessory buss in the fuse panel.

You must be careful because NONE of the ignition switch/ ammeter/ headlight wiring is fused, except only by the fuse link. The headlights have a breaker in the switch

The headlight switch:

You have unfused main power coming in feed ONLY the headlight circuit. In and out of the light switch, then to the dimmer, where it splits in two outputs for hi and lo

Tail/ park, and dash light power goes INTO the light switch from the tail fuse. Instrument lamp power comes through the twist lamp dimmer, and down to the inst fuse in the fuse panel. THIS FUSE then is an oddity. From that fuse, all cluster illumination comes out on ORANGE wiring
