Hey guys, I am swapping out a QSI decoder from an Atlas gold loco and putting in a Tsunami decoder. I have the old decoder out and I am curious which wire is the positive on the motor leads. There is a brown and orange wire. The brown one makes contact on top and the orange goes down the side and I assume it connects to a brass strip. I just want to make sure I do this right. Thanks for any input!
Also, does the leads for the trucks always go on the same side of the decoder (ex. the left side lead goes on the left side of the decoder)??
