Digitrax Decoder Installation For PROTO 2000 E6/E7 with Mars Light With P2K 8 PinPlug/Light Board in HO Scale Remove 8 pin dummy plug from P2K light board
Unsolder the yellow wire from pin 2 and re-solder it to pin 3 (empty pin) on the decoder harness plug. We strongly recommend that you mark the decoder and/or harness so that you will remember that you have modified it. If you use the decoder and/or harness modified in this manner in a different locomotive, your lights will not work correctly.
Plug the decoder and harness into the light board in the locomotive.
Program CVs as follows: CV33 = 001, CV34 = 003, CV35 = 002
Use F1 to control Mars light on/off.
