RECON Truck Installation Guide for 264342 SeriesCab LightsThis kit is for trucks that currently do not have any cab light installed on the truck.First, you will need to measure and mark the roof per the measurements on the second page of thisguide. Once, you have the measurements marked, you will need to drill small pilot holes for each of thescrews on the lights. Then drill a 1/4ā hole for the wiring and plug to fit into the roof.The wire harness will have a positive wire and a ground wire. The positive wire will need to beconnected to any running light positive source on the truck. Most newer Superduty trucks have a 4 pinconnector at the footwell area below the A pillar that has this running light wire(even if the truck has noOEM cab lights). This is where we recommend making the power connection, but any running lightsource will work(and make your new RECON cab lights turn on with the headlights). You can connectthe ground wire directly to the body of truck.
