Re: thumb tilt on omc control box it has no relay its direct, it does have a second rocker switch in back that does work in both up and down positions so i traced power back from that switch and no power on the green wire coming out of thumb switch, that is why i assume its the switch, there does not seem to be a way of accessing switch without removing control box, in thinking of just adding.

PREFACE
This flush mount, alternator tachometer is designed for use on the following:
Johnson® and Evinrude® Outboards
OMC Sea Drive® Models
NON-BRP products with 20 pole alternators
Installation
Disconnect battery cables to help prevent arcing or damage to equipment.
Select a tachometer mounting location that is in full view of the operator.
Drill a 3-3/8 in. (86mm) hole in the dashboard.
Mount the tachometer so water will not collect on the face, or drip on the case and wires. If the tachometer is covered by a transparent shield, the shield must be adequately ventilated to help prevent sunlight heat soak damage.

1968 THRU 1972 Outboards
If you are replacing an older Battery CD Ignition tachometer, or if the engine has never had a tachometer, move the engine harness gray wire to the rectifier yellow/gray circuit on the terminal board.
1978 and Newer Outboard and OMC Sea Drive
Use a wiring kit to connect the tachometer to the plug-in connector on the remote control or accessory electrical cable.
Use Plug-In Connector Kit P/N 0174732 when installing tachometer only.
Use Plug-In/Fuse Block Kit P/N 0173611 when installing tachometer with other accessories.
