Here is my plug , it should be the same. My wire colours are slightly different because its a different year and model but I suspect they still use the same plug (It wont have the PG, Pulse Generator label on it though !)

Hi Steve
I've had a quick look at the ignition control module plug and the wires, i'm now pretty sure i know how to wire them. I've found the plug from the engine you are talking about, two wires come out and go to the ignition control module plug which are the pulse generator wires. I'm still not sure how to get a neutral light.

Steve Asterysk has what Honda calls an
2000 S1100AY Pan which came with nothing for police use.
It's a modified, non-police ABS II model; the modifications are for police.
Merv has what Honda calls a
2000 ST1100PY police Pan,. It was wired at the factory for policie use.
The wiring loom diagram for it is, I think, in the Honda police service manual supplement. Merv might want to obtain that.
Merv might. want to access the diagram for Steve's bike, but that diagram is about half again more complicated than is Merv's.

Hi Merv, as @DaveWooster mentioned you have a slightly different wiring harness, however, we can just go to fundamentals
Below is a photo of the neutral switch, I have also included a photo of the oil pressure switch.
If you look at the gearbox you should be able to see a single wire coming from it , possibly Light green ( or a wire with green in it somehow because its a switched earth)
There aren't too many wires in this area of the engine/gearbox so with a bit of hunting you should be able to locate all 4 (PG,PG,OIL,NEUTRAL)
Most important though to find both Neutral and Oil Pressure so they don't get mixed up
the oil pressure switch

Hi Steve
Found both switches, still not sure how to wire for a neutral light after trimming the ignition control module.
Merv
Glad you located it. What colour is the wire coming from the neutral switch on your bike ?
Now cut the neutral wire (the one attached to gearbox part of engine) and connect to the Lightgreen/Red wire at neutral bulb (assuming you're using the existing instrument cluster). The neutral switch connects the neutral bulb to earth whenever the gearbox is in neutral.
We will need to supply 12v to the instrument cluster but can do that later
You probably want to connect the oil pressure switch to the instrument cluster also , cut the wire from it and connect to blue/red wire at the oil pressure bulb

Hi Steve, Hope you are still around.
I will be running the trike as a naked so the original instrument cluster wouldn't look right. So i purchased an Acewell Digital Speedometer, model number ACE-6556.
Would you have an ideal how to connect the neutral and oil pressure switch to this instrument .
Sorry to be a nuisance.

Hi Merv
Is this the correct manual for your speedometer ? http://www.acewell-meter.com/wp-content/uploads/2017/06/ACE-6XXX-EN-ALL-20170626.pdf
I'm hoping not because it doesn't provide the information needed !! hopefully you have access to a more informative manual
What we need to now is this : for neutral light and oil pressure switch, are they ground switched or +ve switched. There might be a clue on the terminals or in the device software menu, however, it is also easy to determine with a multimeter; just power the speedo and test the voltage from the neutral light terminal to earth , if there is a voltage it is a -ve switch, do same for oil pressure
Once we know that info we can work the next step

Hi Steve
Yep, that's the one
Hi Steve
Yep, that's the one.
I do have another bit to it , I'll see if I can attach it to this message.

Perfect, thats exactly what is needed , your diagram confirms that the Speedo is expecting ground switching, here are the connections for Neutral and Oil Pressure:
| From your ENGINE | Ace SPEEDO | ||
|---|---|---|---|
NEUTRAL | Light Green wire from Neutral switch | connects to | Dark Green wire on plug 'a' |
OIL PRESSURE | Blue/Red wire from Oil Press Switch | connects to | Light Bue wire on plug 'a' |
Watch out , the diagram refers to plugs using both A and a , its the little 'a' that I am referring to (the Male from the look of the diagram), i.e. the plug that will just have loose wires dangling from it
From memory, the m-unit can also accept oil pressure, presumably to prevent ignition until the oil pressure has built up, you might want to splice a wire from the oil pressure to the m-unit also

Thanks Steve
You have been a big help, collecting a few more things and waiting on some internet orders for this project and then I'll make a start.
If you get a chance to post a few photos as your project proceeds we can follow along on your journey, its a really interesting project
I see what I can do

Would anyone know of a domed nut that would fit my steering stem

What you can use is a Chrome Nut cover, Harley/Cruisers use them to cover large nuts and make them chrome.
I did it to one of my Steering Stems on an ST1100
They will probably be in Standard sizes but you can convert to Metric
EDIT Take a look at Billet Chrome show caps or Axle caps

Thanks , all I can find is car wheel nut covers. I was wondering if a domed nut of another big honda would fit. I know the one from a Suzuki bandit wont fit, it's to small.
