speedometer

'74 is a little different because of the seat belt interlock wiring.

The bottom 3 lights have a common feed terminal. This is a Blk wire which goes to the fuel gauge vibrator. From that point, there is a Grn wire to Fuse # 12. There may also be a Blk wire to the brake warning light.

Next, the ALT light has a solid Blu wire.

OIL light has a Grn/Rd (could be Blu/Grn).

Turn Signal indicator has a Blu/Rd.

The 2 lamps that light the inside of the speedo are Gry/Rd.

Hi-beam indicator is Blu/Wh.

'73 Std didn't have rear window defogger, so ignore that one.

The wire from the fuel tank sender to the gauge may be Yell or Wh.
