[6pack] OD Inhibitor Switch

[Navarrette, Vance]

        Folks:

        Thanks for the tips. Here is what I have learned:

        Revington TR offers a kit which requires a momentary contact switch.
It looks like it consists of two relays, a socket, and instructions for
approximately 65 pounds UK. If you get the recommended switch, add 62 pounds,
for a total of 127 pounds or about $180 US.
        Racetorations UK offers a solid state kit, but they do not have the
details on their web site so I cannot determine the cost. I wonder if it might
be the same or nearly the same as the module that Rick Patton mentions below.
        John Williams has a wiring diagram in his book "How to improve the
TR6". It appears to be the wiring diagram for the Revington kit on a car with
the A type OD (since it shows a relay being used to engage the OD in addition
to the add on OD module).
        If anyone can help with details of the racetorations module, I would
appreciate it. In the meantime I have started sketching out a circuit. The
goal is to have it plug in with no cutting or splicing required, and to work
with the existing switch. It is a challenge due to the "no cutting or
splicing" requirement. I want to simply plug it in to the existing harness. A
guess would be that I can get the parts together and build it for 1/3 the
revington cost. We shall see.

        Cheers,

        Vance

Hi Vance,

As Aaron mentioned earlier I have exactly what you've been looking for.
It's a little solid state black plastic box with a series of colored
LED's. Mounted out of sight under the dash the led's are for trouble
shooting and status. And as long as things work properly you don't need
to see the lights. I purchased it from a fellow in Britain a number of
years ago after seeing it mentioned in these Forums. At the moment I
can't recall his name and he may not even offer them anymore. It does
make the overdrive behave like the Volvo.
