Hi there!
I just got a used IBZUSA F3 Pickup off ebay and I'm now working on putting it into my guitar.
The V2 has three cables; Red, White and Silver-ish (I'm assuming that one is ground plus the minus pole)
The F3 has FIVE cables:
Red, white, green, black and ground.
Using the colorcodes at
http://www.guitarelectronics.com/colorcodes.html and assuming the IBZUSA colors are the same as Dimarzio colors I came up with the following:
1) Red Cable: put it where the V2 red cable was
2) Green: put it where V2 white was
3) White, Black + Ground: Solder together and put it where the silver V2 Cables were.
So, I'd appreciate it when some of you guitar gurus could check this before I grab my soldering Iron.. Thanks in advance!!
