Default M40 downshift switch

My maiden voyage last year my downshift worked when I tromped on it. It's never worked since. It's the only thing on my whole frame off restore on my 72 Lemans vert that hasn't worked. I checked the wire terminal by accelerator pedal and the orange wire has power. Going under to the 400 auto trans there are two electrical connections. I assume the forward one on side or the one at rear by speedo cable is where I need to check for power again. The other switch must be wired to my TCS that I have unplugged and don't use. I did push the switch bar forward and then pushed accelerator pedal to floor to set as manual stated. Maybe my switch is bad or the one in tranny. Anyway, manual doesn't tell me where to check for power on tranny to see if above switch is working.
