Rigging

[thomas2729]

I am upgrading from a 1999 Yamaha 115 HP 2 stroke to a 2004 F150.
My question while I have purchased a new digital tach, what wiring harness will I need. will any of my existing 115hp harness, wiring etc work with the new 4 stroke?

Thanks for any info.

Depends on which tach you bought. If it's the 6Y5-8350T-81-00 then only thing you have to do is set dip switches in back of gauge to 4 stroke engine, 2 wire trim sender and 12 pole alternator. If have a 6Y5-8350T-82-00 or newer tach then would need 6Y5-85335-10-00 adpater harness in stalled at engine side of Trim/Oil harness.

How many ivory nylon connectors does you tachometer have? One or two?

[thomas2729]

It has two.

It has two.

Good. It should be plug and play. Two nylon connectors on the motor, two nylon connectors on each end of the trim/oil harness, and two nylon connectors on the tachometer.

As stated by boats.net, set the tachometer dip switches to four stroke engine, two wire sender and twelve pole generator.

A set up card should be included with the tachometer. If not, see below:

Hope he does not get confused, chart does not show a 4 pole

12 pole should get it done

DOH! My mind was stuck on four stroke mode. I guess.

No Problem

I looked at my tach against the schematic and all is well.

Ths again !!
