1993 johnson 40hp tracker vro motor power tilt/trim installation

[wnts2ride]

hello, new member and first time poster. I have a 1993 40hp johnson tracker vro motor, recently took the vro off and am very satisfied with the outcome. Now im working on putting power tilt/trim on the motor due to the current tilt assist unit on the motor being locked up and unrepairable, I have bought a working unit that came off a non working motor. My question is does anybody have the instructions on how to install this on the motor, mainly where to run the wires and hook them up. I was told this is a pretty simple process and should be able to manage this on my own.

Does anybody have a manual with this in it that they could forward me? Or has anybody ever done this before? I've tried searching through other threads to figure this out but they are all for either bigger engines or older engines. I know how to get the old assist off and how the new one fits on the transom mounts. but don't know where to run the wires or where they hook up or where to put the relays. Any help is greatly appreciated. Or to be steered in the direction of where I can find out all the information I need. The local shops all say that this is a six hour job at $80 a hour I cant fathom how this could possibly take that long.

Install time for me is usually around 30 minutes plus however long it takes to
mount the switch and run a pair od wires back to engine.

You need a double throw switch (on-off-on) that springs back to the middle (off) position when you let go.
any switch from any mfg should work fine. pick the one that fits into your boat console best.
Your boat wiring may already include trim wiring from console to engine.
Look for unused wires and check them with the wiring diagrams in your manual.

If you have existing wiring then OMC makes an enclosed relay box with matching connector.


If no existing wiring then you may not want the OMC relay box. It is the same wiring as a generic trim harness except with a mounting box.
I personally think the box does more harm than good. It collects moisture and adds additional connectors to corrode. It is noticeably less reliable than others.

If generic wiring then you need to run 18 or 20 awg 2c from the switch to the engine.
You also need to run a red primary wire from fuse panel to the switch.
Protect switch power with small fuse. Working draw will be less than 1/2 amp.
get a generic trim relay harness - they are often sold as "3w to 2w trim conversion harness".
they usually lay loose in bottom of engine pan or attach the starter bracket with mounting tabs.
