The V1B has 8 Aux outputs for lights. Eight are present on the small connector board and two are paired to the motherboard and associated with the frame (Fx5 & Fx6). The track and speaker pads stayed the same size. The pads on the small connector board got a little smaller. These pads are all separated and have holes to help hold the wires. The stay alive pads moved to the other side of the motherboard out from under the decoder and are in an easy place to solder to like the original. From a little closer to the situation than I used to be, I might say a Steam / Diesel split might align with the two Decoder Buddys as well as a 1997 date split between the two due to ditch light requirements by the FRA. Both are exactly the same size. You get to make the choice! Fortunately both Decoder Buddys have been accepted by both installers and modelers.
