tr-6 overdrive conversion

[TR250Driver@aol.com]

We are doing a overdrive conversion on a late 71 tr-6.  It is an A type 
overdrive and requires it's own relay.  None of the books show were the 
overdrive relay was located.  There is already 2 relay's located next to the 
fuse box.  I was wondering if you could tell me were the third (ie:  
overdrive) relay is supposed to be mounted.

Thank You,
