Car Hauler Winch Battery Disconnect, 2018 Chevrolet Silverado

https://www.the12volt.com/12voltimages/posdoortrigs.gif So instead of positive door triggers, we have positive in and out winch triggers. This will give us a positive output on the 'to alarm positive door trigger input' when the winch is operated...positive winch trigger. https://www.the12volt.com/12voltimages/starterkill.gif Now instead of a starter kill, we'll call it a charge disable. Terminals 86 and 85 are the coil of the relay. Terminals 30 and 87a are the common and normally closed contacts. Normally closed means the current will flow through when the coil is not energized. Terminal 86 will connect to the positive winch trigger. Terminal 85 to battery ground. Terminals 30 and 87a will splice inline on the battery charge wire, terminal 30 to the trailer side, terminal 87a to the battery side.
