2003 40tlrb

I need help finding the correct ignition switch assembly for a 2003 40TLRB

Even the marine dealer says there are a couple different switches used on that model. How do I determine the correct one to buy?

Depends, if you have 703 side mount control with key switch in box then use number 44 in this diagram 2-stroke Rigging Yamaha Outboard CONTROL STANDARD SIDE 703 PUSH Diagram and Parts
If you have binnacle control box with key switch mounted in dash use 704-82570-08-00 Switch Panel assy
