OD Wiring

[Colin Thom <colinthom@shaw.ca>]

Hi Gang,
 
I've installed an OD box into my non-OD early 75 and don't know how to
connect the wiring loom to the 3 inhibitor switches on the Tranny. I
can't find this on any of the wiring diagrams I've got. Can someone
help? Also, I understand that not all OD-equipped cars had an OD relay.
The new wiring harness I got for the car does not have wires for an OD
relay. Do I need one and if so how do I wire it in to the OD switch on
the column? Thanks, Colin Thom CF31098
