Need help with Boss HM-2!

[job]

I have the board and box for HM-2, but they are separated from each others. So could someone please tell me where these wires are supposed to go. I allready know that 1= hot in 6=hot out, but the wires 2,3,4,5 and 18? total mystery.

2 - red- 9v jack "+" connection, nearest centre of the block next to "-" pin
3 - black- input jack ground
4 - blue- 9v jack "-" connection, the centre pin ( largest point on right)
5 - yellow- input jack sleeve for power on/off
18 -purple- footswitch left side connection nearest to the box side

There you go !

Thank you. But still this piece of .... wont work.
I soldered all the wires, nothing. I took my multimeter, started measuring... After a a few bad words and one beer I accidently put one probe to groud and other one point 17... And voila it worked!
So do you guys have any idea what is wrong? Could someone draw me a wiring diagram or something?
I´m just a stupid Finn who doesn´t understand too much of electronics

Inside mine, "17" is part of a large grey multi core cable going to the "pots"
board.
Perhaps that "needs" to be grounded ?
Did it make the pedal work properly ?
If so just use a new short piece of wire connect to input jack
ground ( two black wires should be going there )
Otherwise, I can't help more .... sorry !

One more question.

18/purple goes to switch. But the other wire from the switch. where does it go?

I would think "ground" ... sorry It;s not with me to take another look !
I do remember It was a black lead, normally "ground" in boss pedals

Thank you all.

I don´t know what i´v done wrong. This thing wont do a thing.

Hey Khas Evets could you take a photo of other ends ofthe wires? I mean on/off switch and jacks. That would be awesome.

Just checked for you, "Black" lead from switch does go to input jack "ground"
which is nearest the box edge.
All other connections are as above !
All I can think of is that with several "bends" of the ribbon cable, you may have
broken No 17 or perhaps others !!
Maybe a new section of ribbon cable is needed ?
