Classic vs. Gen 2 Ignition Wiring

It appears from the schematic that the Classic rebel 85-87 has a six wire ignition.

The schematic I have also shows the 1996-2003 cmx250 has a four wire ignition.

Would it be possible to "adapt" a 4 wire ignition replacement to fit a classic?

Yes it would. The "other two" are for the parking light setting on the switch.Second gen Rebs don't have a parking light setting on the ignition switch.

Doing it well would takes some connectors and some soldering but it could be done.

Looking at the two schematics, you would directly connect the brown and the brown with white wire. Everything else would connect the the second gen switch.
On your classic, the red wire is unswitched fused hot. It would go out the the black wire, which would energize your light fuses.
The dark green and black and wire wire from your classic harness are the off switch, grounding the ignition to kill the spark.

The wires on the second gen switch do not match those colors however.

OK, just so I am clear about this.

Off the classic ignition I have
Dark Green
Black/White
Brown
Brown/White
Black
Red

I see on the schematic the diagram showing the parking lights which seem to connect to brown and red.

My aftermarket ignition has
Red
Green
Black
Black/White

So, when mating up the aftermarket ignition (I know, I need handholding here)
Is this correct then?
Classic vs. Aftermarket Ignition
Dark Green
Black/White- Black/White
Brown
Brown/White
Black- Black
Red - Red

it wasn't clear to me which wire BR/W, Br or Dk Gr I should connect the Green aftermarket ignition to. I understand of course, that while some wire colors are a universal code, i.e., red usually means hot, and on our rebels green is ground. I have no idea what the other other colors mean.

If the colors are the same on the switch, the red is the hot going in and black is switched hot. that turns on your electric power.
The black and white is to the ICM and dark green is ground when you switch to off, it connects to shut down the ignition.

The brown is the tail light. the brown and white is the speedometer light.
Where you see the brown to red connection is for the Parking light only.
That connects unswitched positive to the tail light circuit but only in the Park position.
In the On position, red connects to black. The black wire energizes the headlight and tail light fuse. The tail light fuse supplies power to the speedometer light and a second set of contacts connects speedometer light power to the tail light circuit.
This is the set of contacts the second gen switch doesn't have.
The second gen switch doesn't have a Park position. It is either off or on.

Now if my two wiring diagrams are correct, connect:
red to red on the switch,
black to black on the switch,
black white to black white,
dark green to dark green on the switch.

That leaves the brown and brown white. Connect them together but do not connect them to the switch. It should work.

OK, I think it's becoming more clear
To rehash:
Red to Red
Black to Black
Black/White to Black/White
Dark Green to Green

That part seems obvious.

"Connect the Brown and the Brown/White together".
This part seems less obvious to me.

Thanks Buick Guy!

Here I traced the power from battery through the main fuse to the switch out to the tail light fuse through back to the switch where it turns on the tail light.
Just follow the fuschia color arrows to trace the route on the wire chart.
This is with the classic switch.

If you hook up a second gen switch, it doesn't have that contact set for the tail light.
So that's were hooking the brown and white to the brown wire makes the connection the second gen switch can't.
Since the second gen switch doesn't have a park setting, it doesn't need to do a separate contact for the tail circuit. By completing it yourself, it will just energize the tail light when turned on.
