i really think it depends where the switch is. How accessible it is? Can it be powered without you realizing it?

In reply to a post by spartanbilly Since my overdrive will engage in any gear (including reverse)(long story) and I have not damaged it yet......!!! I did the simplest thing I could think of and it took about 15 minutes. I removed the steering column shroud and tapped into the overdrive switch (white wire as I recall). I ran that wire over to the brake warning light which was not in use as the actual switch on the brake line was broken. Works great and it never fails to catch my attention even in the brightest light.


I did the same thing years ago. Works Great. But I did not remove the shroud. I tapped into the yellow wire at the plug.

The yellow wires can also be accessed from the engine compartment (at leats on mine). Near the firewall on the right-hand side, there are a number of connectors between the dash harness and main harness (?). I tested this point and got voltage when the O/D switch was engaged. But of course, now you need to run a wire from there back to the indicator light on the console.

But that is a much better way of doing it - and means it can be removed just as easily. Also much less chance of wiring damage, and being labelled a DPO at some time in the future!

My dash lights are wired directly, so I put a turn signal indicator in the hole where the rheostat was. It points up and is on when the OD is engaged. For some, it may seem unnecessary, but I appreciate the reminder. It shines pretty brightly, even during the day.

Once you take the seat belt light apart, how do you make the OD ENGAGED lettering??

I bought one of these on Amazon, but haven't installed it yet. I love the idea of repurposing the seatbelt light though!



I don't know. It's always smoked like that/made that sound/done that.

If you have the earlier toggle switch you can gt illuminated toggle switches. Now as i drive several cars and use OD infrequently overall i find the illumination helps me switch back into classic car mode and its a nice to have mod...

You could get a black/chrome toggle switch with an LED in the end. The one I got looks similar to an original Lucas toggle (a normal toggle, not the goofy OD toggle).

I cancelled the dimmer (installed a 5A fuse instead) and installed the OD light (amber) in its location on the dashboard.
