Hi members!

As shortly adressed in my " introduction topic"  I am working on a custom bike based on a GPZ 750 Unitrack from 1983 and so far this forum helped me with a lot of things. Many thanks for that!
But now I'm installing a Mo.Unitt bluetooth on my bike I do run into a couple of problems connecting the reg-rec and ignition and I hope some of fyou can give me some guidance or advice.

Reg-rec (original OEM for the GPZ).
I do have 2 cables left that I am not sure on what to connect. 
1x Brown-White
1x Yellow-Black.
I do expect that one of them needs to be connected to the Mo.Unit, but I can't figure out which one it is.

Ignitor (original OEM from the GPZ)
I do have 3 cables left. One of them should probably got to the Mo.Unit, one to ground and one to an interlock system. 
1x Black
1x Yellow-Black
1x Black-white


Any help is gratly appreciated!

Black/Yellow wire is always to ground on a Kawasaki harness. Brown wire on RR is voltage sense.

These may help :

Reg Rec does not need to be connected to the m-unit.
Just run your red coil wire to the ignition output on the m-unit.

Hi members!

As shortly adressed in my " introduction topic"  I am working on a custom bike based on a GPZ 750 Unitrack from 1983 and so far this forum helped me with a lot of things. Many thanks for that!
But now I'm installing a Mo.Unitt bluetooth on my bike I do run into a couple of problems connecting the reg-rec and ignition and I hope some of you can give me some guidance or advice.

I do have 2 cables left that I am not sure on what to connect.
 
1x Brown-White  IGNITION LIVE (ALSO FEEDS BRAKE LIGHT SWITCHES ETC) FROM "JUCTION BOX"

I do expect that one of them needs to be connected to the Mo.Unit, but I can't figure out which one it is.

Ignitor (original OEM from the GPZ)
I do have 3 cables left. One of them should probably got to the Mo.Unit, one to ground and one to an interlock system. 
1x Black                 COIL TRIGGER WIRE (GREEN AND BLACK ARE THE TRIGGERS FOR THE TWO COILS)
1x Yellow-Black   GROUND
