Installing decoder in b23/b30-7

[browningrr]

I have a b24/b39-7 and gp 40 that are DC. I want to install decoders in both engines. I have Bachmann decoders to install. Do you have an instruction sheet to show where all wires go.
Thanks Robert Browning

It's all standard NMRA wiring at the decoder....just be sure which wire is which in your loco.
