A picture will help. Problem is that on my tacho wiring setup it was 3 pairs of shielded wires. Each pair has a red and white wire so there are 3 red and 3 white wires total (essentially the same way the resolver was wired pictured above) so knowing which wire goes where is not possible simply by looking at the colors. There is a 7th wire (blue) which connects the wire shielding to the case of the tachogenerator. Is each of your wires labelled or are they all just different colors? Also take a picture of the sticker on the tachogenerator to make sure we have the same units that way the information that I'll give you is right for your situation.
