I have a 96 3500 and i replaced the PMD, added a cooler for it and wiring harness extension. I was looking at the wires going to the injection pump and saw one of the wires that connect to the front of the pump had cracked but not completely through so i disconnected the 2 wires and repaired them both just to make sure. somehow when i went to reconnect them the tape had come off that i marked and i dont know which terminal is the positive and which is the negative on the pump. I dont want to reconnect them the wrong way and burn something up. any help would be great.just so there is no confusion its the two wires that has the rubber boot on them and connects to the front of the pump.

The wires can go on either terminal. Does not matter.
