Tony;

The P2K GP20 has a socket to plug the decoder into.

The best advice is to follow the wiring schematic that I believe is published with every Lenz decoder. But if you don't have it, here goes: from the decoder, the red wire goes to the locomotive right side (engineer-side) rail pickup. The black goes to the left side pickup. The orange goes to the motor pickup, usually the bottom one. The grey goes to the other motor pickup.

Be sure you have insulated the motor from the metal frame. The best way to check is to use a continuity tester such as in a volt-ohm meter. Place the loco on the track without power, touch one meter contact to a rail and then touch both motor brush pickups. You should not hear a beep. Do the same for the other rail and both brushes. If you hear a beep out of your meter, then the motor is still grounded. Find out where that is and fix it. Otherwise, you will short out your decoder. Lenze will replace them once for such mistakes. Other manufacturers are not so generous.

The blue wire from the decoder goes to both the front and rear headlights, the white to the front headlight and the yellow to the rear headlight.

There may be a green and a purple or brown wire. Unless you have special lighting effects (like a firebox flicker for a steamer) or some such, you can cut these off short as they are not used.

I have a proto 2000 GP20 Locomotive. I got a decoder for it. The decoder is the Lenz LE103XF.
I am every new at this stuff and would like to know if someone has already done this and if they can give me a diagram were the wires go, or any assistance. I thank you for your time and cooperation. Tony
