Mount the receiver box in a location that will protect it from moisture. Note color coded wires identifying leads for trim up/trim down.

As mentioned, the Trim-In-Wheel system can be installed into almost any steering wheel. Alternatively, Livorsi Marine can perform the steering wheel installation for you. For this installation, we used a Livorsi Momo Spargi steering wheel. Installation is can be performed using a small drill and a soldering iron.

To install the radio transmitter and switches, you must drill the appropriate holes into the steering wheel spokes as needed. The number of buttons is determined by the application and your preference. For our installation, we have four switches – two on each side – that control the trim. The switches are color coded; green for down, blue for up. After the switches are installed, two small holes will be drilled into the top of the hub, just below the spokes. The switch wires will pass through to the inside of the steering wheel hub at this location. Once the wires are in the hub, you may solder the connections to the radio receiver. Alternatively, if you choose not to solder the connections, you can purchase two pin fan PC fan connectors at almost any computer hardware outlet. It might also be wise to bring the radio transmitter with you to be sure your connectors will fit properly onto the pin header.

Once your connections are complete, secure all wiring and test the system. Marine 2000 supplied the stainless steel terminals and wiring for this installation.

The second part of the installation is the setup of the radio receiver. You can place this unit anywhere inside the boat, however we recommend a location that is protected against moisture. Since I already have a wiring block under the dashboard, this is where I chose to mount the trim receiver. Installation is very straightforward – simply mount the box, connect the power leads, and then your connections to the trim solenoids. Although the first two pins are used for trim actuation, the remaining pins remain active, and may be used to trigger other devices.

The quality of the electronic components is very good, and our Livorsi Momo wheel looks perfectly natural with the trim system buttons integrated into it.  I’m pleased to report that there was no interference with the Livorsi trim system at all – it simply functions the same as a wired system it replaces. During testing, it was noted that there is approximately a 250ms delay from the time the trim button is pressed to when the relay is commanded.  This delay will not be a problem for pleasure or casual performance boating, but racers should take note of this.  The trim system was tested in close proximity to various common radio frequency-emitting devices with no resulting interference.

Overall, Livorsi's Wireless Trim-In-Wheel system is a fantastic solution for those looking for the convenience of wireless steering wheel-mounted trim and tab controls, while adding the custom appeal of a system that can be integrated into almost any steering wheel.
