Duster Rallye Dash -- Wiring Help Needed!!

Does anyone have a photo of the back of their 70-71 A Body rallye dash wiring harness hooked up? There's a connection I have that's got a red, light green and orange wire that I see nowhere it can connect and it's nowhere on my wiring diagram. It appears it slips over pins but again, I see nowhere for this to connect to? Then, according to the diagram, I have a connector for a low brake warning switch (by the heater box) that I see nowhere where it could go?? My previous harness which was from a 71 didn't have this switch, so it must be a 70 thing??

Not sure, but the 3 terminal plug looks like the plug for the dimmer switch.

looks like the wrong wire colors for that ?

the connector goes to driver side circuit board next to the speedo
