Clutch safety switch bypass - which wires to jump or connect?

Lux_Bullet

Total noob
Replacing my clutch assembly with an aftermarket one that has no clutch safety mechanism. I've removed the plug from the old assembly and I'm planning on cutting it three inches below the plug so I can reinstall easily if need. Once I have cut it, I'll be left with three wires: BLACK, BROWN, GREEN. Which wires do I solder together to bypass the safety circuit and what do I do with the third wire? I'm planning on just wrapping in electrical tape and tucking the wires back into the headlight nacelle. Photo attached.

Thanks so much for your help!

As far as I understand from the other site (thank you Scottfree and Squeezy) (posts nr 20591 and 20592) all three should be connected to provide a ground for the starter relay.
I now see yours is a Bullet: I was referring to a Himalayan. But I think the reasoning is the same, just check the wiring diagram.

Thank you, Robert. Are you able to provide links to "posts nr 20591 and 20592" or tell me how to look them up? I tried searching the numbers in the forum.

I really appreciate your time.

Here's a schematic, see attachment...

which looks similar to this https://www.manualslib.com/manual/902598/Royal-Enfield-Bullet-Classic-Efi.html?page=211

so you should be able to see what wire you need to connect to chassis/GND to bypass the clutch lever safety protection, (at your own risk, don't put the poodle in the microwave, etc.) and enable starter motor solenoid opration.

Interesting to note NLSW on the ECU: I'm guessing Neutral Line (Light?) SWitch(ed): this would be the primary path to chassis/GND/negative for the solenoid when bike is in neutral, and the wire labelled GREEN would be the secondary path to GND, i.e. in gear but clutch lever pulled in. Good luck with the colours, on my Himmie they didn't match the schematic. You need to connect the wire that goes to the solenoid with the wire that goes to the GND.

Thanks a lot Squeezy. I also found a snapshot of the clutch switch schematic here: https://ibb.co/z5hMRYD.

Yeah I don't trust the colours either. Someone else has said it worked by just twisting all three wires together? Wouldn't that short the circuit? Another forum post showed jumping the plug from the two furthest holes (photo below and this was on a Himalayan) leaving out the middle and that worked.

I just don't want to blow any fuses etc.

the three wires involved are all earth/ground/chassis/battery negative/whatever you want to call it/ at some time or other, either by engaging neutral or by pulling the clutch lever back, so a short-circuit, meaning an unwanted direct connection between two points that should be isolated, usually in our case, the pozzy and the neggy of the battery, isn't going to happen, unless Murphy...
If I was leery of causing a mischief, I'd get out my meter and check for deffo which cable goes where, in case you're from the wrong side of the Pond and sue me for a million dollars. The green cable should bell through to chassis, the black to the solenoid neg terminal, and the brown to the ECU. I'd connect the earthed cable to the solenoid neg terminal cable and check all is kosher, and observe all other functionality e.g. sidestand effect and neutral light with the ECU wire not connected to anything.
[EDIT] don't be worried about blowing fuses: that's what they're for, just never replace one with one of a higher value unless a grown-up has told you it's ok
