Chris,
For the receiver we sell the SuperSwitch ($29.95). This has 18ga wire and a Deans UltraPlug from the battery to the switch (a pigtail and shrink-wrap is included to retrofit the battery to a Deans UltraPlug). For the ignition you can use a regular DSC switch. We resell Cermark DSC switches for this purpose. Also, you did not say what kind of batteries you are running. We also sell regulators if you are running lithium packs. Let me know if I can answer anything else.
