Re: 2005 Yamaha F115 Rigging Guide needed
wont work with the 96 digital tach.
I think the tach has to be an 01 or later that can be set for 2 or 4 stroke and 2 or 3 wire trim sender.
you will need the 05 marine tech guide,the 05 rigging guide and the 05 accessory guide to find all the parts to piecemeal it.
the trim wire and alarm harness can be used but will require an adapter.
the tech guide explains the single connector,the accessory guide shows all the adapters and the rigging guide explains the tachs.
your current 10 pin main harness will work.
