This wiring kit is intended to fully populate all of the inputs and outputs for part numbers 553-111 and 553-112 Pro Dashes. These can easily be inserted into the existing 34 pin dash connector. It contains loose wires and 2 and 3 conductor cable (jacketed but not shielded). There are TE superseal pins crimped on every wire and cable. There are also extra pins that can be used (likely needed when using the jacketed cable for more than one sensor).
