Transom Harness—DTS/Mechanical Shift
This transom harness is designed so that connections can be made after the transom is installed in the boat but before the
engine is installed. Connections made before the engine is installed are:
• MerCathode connection
• Trim connections
• Ground connection
• SmartCraft sensor connections
Secure the wiring and position the engine connector out of the way until the engine is installed.
After the engine is in place, make the single connection between the transom and the engine.
DTS engines are shipped with an adapter to connect the transom harness to the power trim pump.

Transom Ground Connection

The ground wire for the transom is incorporated into the transom harness included with the engine.
Connect the ground wire in the transom harness under the bonding strap screw on the transom. Do not connect any other
ground wires here.
Use the ground studs on the flywheel housing for other grounding needs.
