Overdrive Relay Wiring

[Alpine Bob]

I have a Series IV with OD non-synchro transmission, and the OD switch is just an off/on. I have since purchased a self cancelling OD switch. My question is: in order to use the self cancelling switch I have been told that I would have to rewire the relay. How would I do that? In other words, which wire goes where? All this is because I broke the phanolic (SP) (plactic) on the original, so I installed a regular on/off switch, but I want to go back to an original steering column switch. HELP.

Bob,
You need the self-cancel relay too

Jan,
Do you have a part number and/or a source for the self cancel relay? Could I still use the same harness as I have installed now?

Bob,

The self cancelling relay is a different relay and these are very hard to find.

It is possible to use an open relay and a closed relay (I think) to make this work. Maybe someone can help here. If you can contact Cool Cat Eddie he could help with this.

The wiring harness is different.

Also on the switch up is on down is off.

Maybe I could modify the switch to remove the momentary configuation and make it a on/off switch. Just a thought. Maybe if someone out there would like to trade my self cancelling switch for a nice on/off switch. I have a on/off switch (like a dash switch) wired up now but I'd like one with the long stem. I have the on/off switch but with broken phanolic(sp?).

I do not think you can modify to an off/on switch.

I think Rick at SS has a tech tip on the overdrive relay. You may want to look at that.
