I am trying to help a fellow villager with a defective turn signal module. The module is a Yamaha part, Old style turn signal model: made by Grand General Y00003 / GYA001

Real Yamaha part# GCA JW112-41-01

A search on this number (11/7/23) seems to indicate this is no longer available, out of stock, or on backorder.

Also, I have not been able to locate a wiring diagram for this device, even when talking directly to Yamaha. I have located 2 possible alternatives, one from Signal Dynamics and the other from RHOX, but in either case I would need to splice the new module into the existing wiring. This would save me a 2 couple of hours tracing wires, or more time installing a new wiring harness.

So if anyone has actually found a source for these modules or a wiring diagram for the Yamaha turn signals I would be really interested. I have 5 or 6 hours of internet searching with no results so far.

On a side note Yamaha said the wiring diagram was in the service manual, which I happened to own (400 pages) and it does NOT include any accessory wiring and the Yamaha part number indicates this is an accessory.
