11 wire Signal Stat (Sigflare) 900 wiring explained

[T-Mack1]

Ok guys, while volunteering at the Mack Truck Historical Museum,  I had chance to work on a steering column mounted Signal Stat turn signal module with the rare 11 wires.   Since the internet doesn't show the wiring for them and the unit is obsolete, here is the wiring explained.  

Signal Stat (Sigflare) 900, 11 wire 

Standard wires (also on the on 6 & 7 wire units):

Blue (if present) - Input for internal indicator light (from 3 prong style flasher module, "I" pin)
Yellow - Input from flasher module (blinking on-off)
Gray w/Black trace - Input from Brake switch
Green - to Left front turn signal light 
Red - To Right front turn signal light 
Gray - to Left rear Turn/Brake light 
Black - To Right rear turn/brake light 

The 4 wires extra wires
Red w/Black trace - feeds power to front turn lights filaments when turn lever/4-Way is not active (NC).  Opens appropriate contact when lever actuated and connects it to flasher.
    (use ballast resistor to dim filaments for running/parking lights)
White -  Auxiliary Common (NC)   
White w/red trace -  Auxiliary Right
White w/green trace - Auxiliary Left
   
Notes: 
1) Aux connections are "Normally Closed" (3 white leads tied together). Lever actuation "opens" the appropriate wire/connection). (( I have no clue how this would be used.)) 
2) If you have the blue wire, you need to use the correct flasher module that has the indicator output pin
3) Warning: on most Signal-Stat steering column mounted units, using the 4-way flasher slide bar, disconnects the brake lights. Keep that in mind if driving with someone following too closely.

enjoy,
