Anyone have a TT75A? Need help with tach wire.

[Cw021382]

I just picked up a 2008 TT75A. It’s a decent tractor, but it needs a lot of little things. Mainly electrical issues Like the tach not working. The previous owner had the injection pump replaced, and he said the tach and hour meter worked before but not after he got it back. I believe on this model they are both driven by a single signal wire from the alternator. There is a male blade connector on the back of the alternator, but I cannot find the signal wire that goes to it. I have cut back the harness to the alternator thinking the wire was broken off, but it’s not. If anyone has one of these or a work master 75 would you please take a look and a few pics and let me know where it is and what color the wire is. It would be greatly appreciated. Thanks. -Chris

Finally got my repair manual. I will post the schematic later to help future users.
