You need to select the correct module and adapter for your vehicles. If you are unsure, use the Power Match to get the correct light harness.
This is the Complete Truck Side Fleet Flex Wiring Kit and a set of the 38800 plow lights. This is the same for Fisher, Western, Snowex, and Blizzard plows. This is the 3-port isolation module and the 2-plug setup. This was used on the V plows, the XLS, Wideout, Power Plows, the HT, HTS series plow, and the Series 2 straight blades. These plows use a 4-pin square plug on the control and a 4-pin grille power plug. What you get is the 3-port module, new version of 72168 truck side power cable and 90730 fuse block, 28587 4-pin control harness, 11-pin truck side light harness, and then your choice of headlight adapter to fit your truck. We also recommend getting a tube of dielectric grease to protect these plugs.
Some of the newer trucks require extra adapters and they would be sold at an extra cost.
Note:Only forMultiplexing system. If your control has more than four pins, this is not the right kit for you.
