I have a DCC/Sound equipped locomotive that I purchased last year.   The seller elected to cut the wiring harness between the locomotive and tender vice modify the foam in the box.   I am looking to reconnect the wires.  The locomotive is equipped with what I think is a TSU-750.  The headlight and backup light were grain of wheat bulbs (really small).  I have been able to determine which wire connects to which other wire, with two exceptions.  The headlight wires. Question: Does the Soundtraxx decoder care which side of the lightbulb is the connected to the capacitor and which side is connected to the function output.  My initial thought is no.  Just want to confirm that before I bring a soldering iron near the locomotive.  I only want to do this once, and Im going to put micro plugs on the wires so I dont have to do this ever again.
