I'm replacing the tiller head on a Yale MPW 060, s/n A897, and the new part, a 550013954, is different from what's in it now. (though the tiller head may have been replaced at some time in the past)

It's a Curtis system and the new tiller head has 4 possible positions for its learning jumper. (4 sets of 2 pins) I have a book that shows a head with 2 possible jumper positions. (3 pins in a row)

Has anyone seen a service bulletin for this new tiller head? It also has two different sockets that would fit the wiring harness plug. Any info on jumper positions, set-up procedure, and where to stick the harness plug would be appreciated.

my e-mail is in my profile. Thanks.
