TOPIC: MerControl wiring and replacing new switch

On my Mer 450 I have the wiring diagram and cable, trying to install new aftermarket switch since mine was missing the key and it very corroded

Terminals:
Letter, Color, (function), question
A Green (Battery +)
B Yellow (starter)
D Red (Battery -)
E White (Magneto)
F Black (12v from stator)

where do they go on this Marpac 7-1150 switch, don't want to blow this up.

Marpac switch
Terminal, function, (Merc color)
A Accessory ()
B Battery (Green)
C Choke (Gray)
I Ignition ()
M Magneto (White)
S start (Yellow)

terminal positions per manufacturer
Off (M-M)
Acc (A-
Run (B-I-A)
Start (B-I-

I will tap into the choke button on terminal C so I can use push to choke or the original button

Steve,
See attached pictures.
In one you will see there were (2) color codes used on the magneto engines, then an industry standard color code came into play, and that is what you have on your new push-to-choke ignition.
So be very careful what wire you connect where.
