Re: 1972 wiring diagram
Someone here was kind enough to send me a copy of the correct wiring diagram. Thank you!
Now to the benefit of those that will come behind me. Here it goes.
When dealing with a 1972, the manual may or may not be correct for your specific 1972 engine. There are actually 2 different selectric switches found on these remotes. From the top, they look the same. Flip it over and you will find out if it's an "early" 1972 or later 1972. The manual I bought online only provides the diagram for the "early" 1972. (BTW, I got my money back!)
The later 1972 switch actually has 5 posts found on the back of the switch. In addition, the ignition switch also has 5 posts on it too. I promised not to post this diagram on the web, but I will take the time to explain.
The 5 pole selectric switch is wired in this manner. If the lettering is worn off the rubber, peel it back, it's also stamped in white ink on the bottom of the switch.
1 - White wire and goes to S or ST on ignition switch
2 - White wire and goes to one side of starter solenoid
R - Blue wire and goes to reverse solenoid in gearbox
N - Green wire and goes to Neutral solenoid in gearbox
+ - (This has 2 wires on it)
- Purple/green and goes to #4post on terminal block on engine, then it
continues on to diode assembly
- Solid purple to ignition key.
Seeing this setup is different that what most of the peanut gallery has seen, here is the wiring also for the ignition switch too.

In order clockwise viewed from the back.
Batt - Battery red wire
M- Black/Yellow
S or ST - White
A - Has 4 purple wires
- purple to + on selectric switch
- purple to Choke switch
- purple to one side of the horn
- purple in main harness aft to terminal block #7
The individual choke switch style below the key gets the purple/white
I hope the helps someone out. I spent the last 2 days researching this and someone helped me. thanks for reading, if you have any questions, please PM me and I'll try to help where I can. (airplane mechanic here)
