Pins 1 & 2 are General Illumination return - RED
Pins 3 & 7 are Feature Lamp Bus - BLUE
Pin 4 - KEY
Pins 5 & 8 are General Illumination Bus - WHITE
Pin 6 is the Solenoid Bus - BLUE/WHITE
looks like your Pin 1 is red and the first pin in the connector isn't used and goes to the left of the header pin 1
you could leave as is but maybe put in a keying plug in pin4 and pull out that IDC pin on the far left and cut that unused section off?
replace it with a Molex KK type using trifurcon pins?
