Yeahyeah, they gay, but ive just had a hunt around the house and found FOUR, yes FOUR of them

1st one is a MikeR original that I had on my Cossie, it has 4 wires.
White, Brown, Yellow, Blue.
What goes where?

Others have 5 wires tho and are all brand new, fuck knows about them, anyone know? Im guessing they them gay ones that cut the ignition or summat?
