Each kit includes all the basics needed to rewire a vehicle from headlight to tail light and will accommodate popular add-on items such as electronic fuel injection, aftermarket gauges, and common supporting modifications. This kit is compatible with Suburbans but will require a 510901 Suburban rear body add-on.
