I ordered the SDH164 decoder with the 8-pin to 9-pin harness. My problem is that I don't know which pin on the harness' 8-pin connector is pin 1. Don't want to plug it in backwards and burn something out.
Pin 1 on any manufactures decoder harness is the orange wire. The NMRA standard 8 pin plug diagram is found here. http://www.mrdccu.com/curriculum/basics/ready.htm
Plugging an 8 pin plug backwards will not do any harm. The loco would run backwards and the lights will not work.

I pray every day I break even, Cause I can really use the money!
I started with nothing and still have most of it left!
Thanks, Pete. Much appreciated!
