red = positive
black = negative
green = negitive coil
white = parker wire

lol just run the red wire to the positive battery terminal
run the black wire to a bit of metal under the dash
with the green wire run it to the coil you will see a little - mark on one of the 2 terminals
now your parker wire is usually a dark purple or violet colour best bet would be to get a test light and try and find it under your dash if you think you found it turn the parkers on and off and if your test light goes on and off you know thats the one but best place to look for it would be in the light switch wire loom

you're better off hooking the power wire (red) to accesories, ie. cigar lighter, clock, stereo, etc... As for the light, an idea would also be cigar lighter, clock as it then the brightness of the tacho light can also be adjusted/dimmed...

VY CUSTOM.
This is just a tip#

When using the 12v accessory in the fuse box, make sure your key isnt tunred to far fwd, i've noticed with mine being 1/2mm to far fwd wont activate the 12v access.

So if you think your connects have an outstanding stable hold, and nothing isn't happening.. just make sure your key isnt that extra bit fwd. :D
