***That is a hard oneto answer without knowing the specific loc, as some 8 pin plugs are oriented front and rear and others are set aross the loco... and a front left becomes a front right when the plug rotates 90 degrees!

A simple aswer for you:

There should be a star, a 1 or a mark of some other kind to show pin 1.

if you get it right, the loco will go forward when you tell it to and the lights will work directionally/properly (turn on with function 0)
if you get it wrong, the loco will go backwards when you say forwards, and the lights will not work.

you will NOT damage the decoder if you put it in the wrong way around... so look first, and if U aren't sure, just try it.

Regards

Richard

Thanks for the info Richard, I found the number 1 under the choke.

I have sucessfully fitted the sound chip into the tender of my bachmann 9f as there is no room in the firebox.
The chip socket in the loco will reach to the space by the fire box so that the sound chip plug will reach from the tender without much trouble, I only had to unsolder the wires from the plug, pass them through the hole in the floor where the tender top clips in and re solder them to the plug.
the chip is taped to the side of the tender top and the speaker is stuk to the water filler end.
The ballast weight is also removed to cleaar the chip, I have stuck in 45 grams of alloy wheel balance weights ( same weight as the ballast plate. ) leaving plenty of space for the speaker and chip, all thats left to do is paint the wires black to hide them, job done.
.

hope this info will give someone the nudge they need to try fitting sound to their 9f.

ITS FANTASTIC
