Left side handlebar switch question?

Only thing that has changed since I first completed the wiring is I have connected the coils - horn.I'll check the brown & brown/white wiring as you have flagged it up Ken.
I will remove the headlight and have a look at the Spaghetti - I need to make a proper record of my wiring as the odd wires are not as per the wiring diagram colours due to having the wrong switches.
If push comes to shove I will disconnect the parking light as I have never used them on a bike or a car for decades.
Obviously I would prefer them to work so that option is the least desirable.

Now that you've mentioned 'horn'. Realise the horn was wired differently for different markets. Consult the appropiate wiring diagram.

I have wired my Horn so one side goes to Earth the other side is connected to faded wire looks like pale green-blue at the point in the loom that has the coil feed wires - same colour comes out of the main loom at the headlamp end where it connects to the horn push button of a similar colour.
Horn works as it should - everything works fine until I move the right hand bar switch from 0 position to either P or H then with the key in the far right position to leave on the parking lights. With switch at O everything is normal - then if I move the right bar switch to P or H then the ignition comes on.
I suspect that the fault lies in the power feed to the lights somehow powering the ignition.
I have eliminated the ignition switch being faulty as I tried a new spare. I am currently checking & documenting all the wires in the headlamp bowl.
As I do not have the correct bar switches I do have a couple of wires that are connected against the colours to make everything work.
I suspect these are the route cause of my back feed.
I have made a bridge to connect the following wrong colours:-
Left bar switch (Male Bullet) Black/Yellow Trace to Right bar switch (Male Bullet) Black/Red trace.
Lastly this is probably the problem area.
Main loom at Headlamp end has a Black Double female connector block (live via ign switch).
This 4 way block has following connections - all male bullet connectors.
Black wire to the Left Bar switch.
Black/grey trace to right bar switch.
Black/Blue trace to right bar switch.
Kojaycat sell an A3 laminated coloured wiring diagram for the 500 - I have asked them if it is the correct for a 500 K1 - waiting for a reply.
My switches are for the CB400 /500 K2 / 550 F1-F2 purchased in error tbh but think I can make them work.
Oddjob:
ONLY black wires should be connected to black loom wires, nothing else, no black with any other trace colours.
Are you slightly colour blind Ted as I can't see any black/grey or black/blue wires in the wiring diagram for the 550. There's a black/yellow and a black/red in the headlight wiring and a brown/blue but not the colours you've listed. Disconnect them and see if the problems stops.
And yes I know yours is a 500 but the switchgear isn't.
Oddjob:
From what I can make out Ted, the park position makes the brown wire live. It should only feed the rear light by rights, if you've connected any brown/white wires into that bullet connector then the would make all the brown/white wires live when the switch was in park. Any position on the headlight switch (except off) on the right hand switchgear would make contact with that wire so any wire connecting to that would also become live, hence why the whole system starts to power up.
Black/Yellow is the feed for the lights on the 550, it's gets it's power from the 3 fuse box via the headlight fuse, that's powered by the black/red wire, it's wired into the starter button, so that when the button is pressed the lights go out to avoid drain on the battery when the starter is spinning. Not a feature the 500 had, so you may find the lights also going out when the starter fires up. You could just wire the black/yellow into the black feed and that would also work. In this case that's ok as it's a compromise on getting 550 switches to work with 500 wiring.
