Rigging 90 2 Stroke

[mp]

Switching from Mercury to Yamaha 90 @ stroke, using Livorsi controls, my boat has a push button strating with toggle switch. Would like to keep the push button and toggle switch. I have the new 90, only have 10 pin wiring harness, what else will I need? Can I use my existing analog tach. The Livorsi controls have the tilt and trime switch built in.

Thanks

I don't know about the rest of the controls but the 90 yamaha requires no choke control it is all automatic. Just leave it in neutral and don't give it any throttle and it will start in a few seconds.
