Let me start off by saying I an completely new to thi . I know the basic stuf . I used to rig boats a while back when I was younge . I just bought my first boat. Bought my dad's 2000 nitro that's been sitting in his garage for about 3 years and hasn't been touched. The wires for the trim switch on the throttle had been chewed in half. this may be stupid but where do I connect new wires???

from trim switch in handle, the wires go down the handle to the wiring harness. from there its run to either the trim gauge assembly or back to the control relays (depending on the particular trim)

many times you have to completely pull apart the controls to feed new wires.

Since you have a new trim switch one must assume the wires were chewed near that switch or at least the existing wires are still attached at the switch. If needed, splice new lengths of wires from the engine side of the harness and attach them to the same terminals on the new switch. You don't need to run new wires all the way back unless the critters got really busy.

Could I just splice into the wires coming out of the trim switch on the motor

no, you are confusing low current with high current circuits. usually the switch runs a pair of relays. the relays control the motor.

Here is typical wiring. the little rocker switch can not handle the 50 amps of current of the motor

switch goes to relay module or individual relays.
