	Fig 1: Remove the shell by spreading the sides by the tanks and lifting off.
	Fig 2: Use a knife to cut the PC board traces at the three places marked by an “X”. See the photo for their location.
	Fig 3: Using the plain wire harness that comes with the T1, cut the leads to length and solder to the PC board as shown: Orange to P1, Red to P8, Blue to P7, White to P6, Gray to P5 and Black to P4. Fold Green, Yellow and Violet back out of the way and tape to the decoder. You don’t need the blue and white wires for a B Unit, but the same decoder and method can be used on an A unit with lights.
