Abstract: A wire harness and method for manufacturing thereof are provided. The wire harness includes a plurality of wires, a terminal member, an inverted sleeve, and a high temperature moisture resistant sealant. The plurality of wires includes one or more wires with protective layers of metal and fiberglass and skived Teflon tape as a moisture barrier where at least one end of the wires with protective layers of metal and fiberglass is connected with a terminal member. Protection from moisture is enhanced by enclosing at least one end of the wires with protective layers of metal glass with the inverted sleeve. The inverted sleeve provided has ends where each end has a fold, thereby preventing frayed edges from being exposed to the sleeve's surrounding environment. The inverted sleeve is coated with a high temperature moisture resistant sealant and encloses junctions between wire ends and terminal members and/or junctions between terminal members.
