Hi!
To echo what Bill and others have said, you should not ignore this
switch, mainly because engaging overdrive in reverse can be
catastrophic.
I don't know what gearbox you have, or if it's easy to fit this switch
to your gearbox. If it's not easy, an alternative is to replace the
switch with a relay. Connect the secondary circuit of the relay to the
reverse light in such a way that when the reverse light is on, the relay
will open, thus preventing you from accidentally operating the o/d.
Good luck! Let me know if you want more information.

The switch on the gearbox is an inhibitor which allows overdrive to work
in
3rd and 4th only. The lower gears won't be so much of a problem (though
overdrive is unlikely to work very well in those gears due to reduced
operating pressure) but operation in reverse is usually catastrophic
because
of the one-way clutch. Trust me, you really don't want to bypass the
switch......
Cheers,
Bill.
