Where are these wires? (gear shift indicator wire splicing) (1st gen)

Folks, where is the best place to splice into these wires? This is to instal a cheapy gear position indicator LCD.
The gadget has these wires:

• Black cable is for -
• Red cable is for +
• White cable is for neutral (0)
• Yellow cable is for the first sensor cable 1
• Green cable is for the second sensor cable 1
• Blue cable is for the other cables of sensor 1 and 2 together

I can figure out the black & red but am hoping for opinions on the white/yellow/green/blue.

NEVERMIND!
The sensor cables are not something coming from the bike. They are coming from magnets that are in the kit. So I only have to wory about positive, negative and neutral cable splicing which are all easy enough to find.
