I’m going to have a few posts coming up about wiring, but…

Before any discussion of wiring begins, buy this product: the VEX Extension Cable Retaining Clip. It’s cheap: $4.99 for a 10-pack. It is, hands-down, the best product you can buy from VEX. It’s just a little u-shaped piece of plastic, with a gap along the long edge. You take your cable junction and wedge it into the clip and it will NEVER COME UNDONE by accident. Without it, these plugs come undone in about 2 seconds, and the pins themselves are extremely fragile and break or bend quite easily. Before they created this product, your best bet was to tape the junction, which tends to come apart over time anyway and makes troubleshooting difficult.
