Help identifying wires on a hotrail.

Help identifying wires on a hotrail.

I got this cheapo pickup to put into an acoustic guitar for giggles. It did not come with any wiring instructions.

Can anyone help me identify which leads are meant to connect to which parts? It's a single-pickup circuit connecting to a volume, tone pot, and output jack.

Psychic ability not working today.

Every pickup manufacturer seems to have their own color code for wiring. You need to contact the pickup maker.

Haha fair enough. I was thinking that perhaps due to the location of each different colour wire it would be possible to work out for those in the know.

Well, since only 3 wires are on the switchplate end, I bet one is common (ground) and the other two are the other end of the two coils.....

Do you have a DMM? Measure resistance between each pair of wires, at least this will let you know which pair goes to each coil. Then wire them in series one way (e.g. if the coils are green-red and white-black, wire green to ground, red+white together, black is hot) then the other (e.g. green is ground, red and black together, white is hot) and see which one gives a hotter and fuller output (=coils in phase). Since I guess it's the only pickup on that guitar, you don't have to worry about overall phase, just between the coils.

BTW for an acoustic you may also like parallel wiring, so in the example above it would be either green+white to ground, red+black is hot or green+black to ground, red+white is hot. It will have lower output but still cancel hum and give you a more single-coil-ish sound.

Here for the gear
 

it's probably like this:

Red: + (or the hot wire)
White: -
Small black wire: ground
Thick wire: green and black wire (as seen on the backside of the pickup) wired together (these wires can be used for coil splitting etc.)

The thick wire could also be a shield tied to ground.

Guessing about the thin wires is just guessing - I've seen pickups from various makers that used black, red, and white (not at the same time) for hot.
