There is a small hole in the auto trans collar for a lightbulb. The bulb lights up the clear shift indicator lens at night. The red pointer is not lit. | | | | | Joined: Mar 2001 Posts: 1,181 'Bolter | | 'Bolter Joined: Mar 2001 Posts: 1,181 |
Yes the Hydramatic has a small light just behind the indicator.

RE: 1964 C-10
The gray wire from the gear indicator light socket in the steering column flows thru the dash wiring harness directly to the fuse box, where it is connected into the "GAS GUAGE EXT" along with the tan wire from the fuel sender unit (coming from the gas tank).
The gear indicator light will not illuminate, nor does a test light in the socket illuminate. My fuel guage works.
What's my next step in solving the gear indicator light issue? | | | | | Joined: Sep 2003 Posts: 2,384 Shop Shark | | Shop Shark Joined: Sep 2003 Posts: 2,384 | IIRC, the gray wire should plug into the harness at the base of the column. You could also hook it to the PANEL fuse. | | | | | Joined: Jul 2001 Posts: 3,887 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Jul 2001 Posts: 3,887 | gray wires are dash lights, as Brian sez, hook it to the power for them, you don't need it when the suns up  Bill | | | | | Joined: Aug 2000 Posts: 800 Shop Shark | | Shop Shark Joined: Aug 2000 Posts: 800 | Did you test it with the headlights on? | | | | | Joined: Sep 2010 Posts: 100 'Bolter | | 'Bolter Joined: Sep 2010 Posts: 100 | yes, tested with the headlights on. No results. I know the socket get power and the bulb burns when I disconnect the gray wire for the socket and plug it in directly to the fuse box. | | | | | Joined: Jul 2008 Posts: 1,262 Shop Shark | | Shop Shark Joined: Jul 2008 Posts: 1,262 | Why not just splice into one of the existing gray wires that powers the gauge cluster lights? | | | | | Joined: Apr 2011 Posts: 12 New Guy | | New Guy Joined: Apr 2011 Posts: 12 | Dash wiring diagramHope this helps. I can't see what you're encountering. Good luck.

| | | | | Joined: Sep 2010 Posts: 100 'Bolter | | 'Bolter Joined: Sep 2010 Posts: 100 | Ok. Solved. I really did not want to splice into any part of the wiring harness, but was curious as to why the socket wire was wired into the fuse box in conjunction with the gas tank sending unit wire.
Ran the socket bulb for the gear shift indicator to the fuse box and connected it to a separate terminal on the fuse for the dash panel lights. Works only with the lights on and also now has light dimming feature, just like the dash lights.
Thanks for everyone's suggestions! | | |
