I'm woundering what a T53 is I did a search on Humminbirds website and found nothing

try TS3. Second character is a letter "S" not a number "5"

Connecting the Power Cable

Connect the Transducer Switch power cable to the boat’s fuse panel (usually located near the console). If you must
connect to a battery, connect to a battery switch (not included).
1a. If a fuse terminal is available, use crimp-on type electrical connectors (not included) that match the terminal on
the fuse panel. Attach the black wire to ground (-), and the red wire to positive (+) 12 VDC power. Install a 3 amp
fuse (not included) for protection of the unit. Humminbird® is not responsible for over-voltage or over-current
failures.

or...

1b. If you need to wire the control head to a battery, obtain and install an inline fuse holder, a 3 amp fuse (not
included) for the protection of the unit, and a battery switch (not included). Install the battery switch using the
instructions provided with it.

NOTE
: If you are unable to obtain a battery switch and are forced to connect the power cable directly to the battery, be

aware that this may cause a slow loss of power over time. See procedure five,
Powering Off.

NOTE
: Humminbird® is not responsible for over-voltage or over-current failures. The control head must have adequate

protection through the proper selection and installation of a 3 amp fuse.

A 3amp toggle switch would work fine in this case... They need to word this better. Autozone has it for $2.00
