The ECU and the rotary switch will plug into pre-existing recepticles in the cowl harness.
The indicators in the dash are also present. you need to pull the instrument cluster and add the indicator bulbs to the pre-existing holes in the circuit board. The front axle wiring is also plug in. You need to get a front axle wiring harness. This will plug into the actuator and then make the trip up to the firewall where it plugs into the cowl harness near the antenna plug.
The rear axle is a bit more challenging. You will need a diff-lock rear axle housing harness that will replace the ABS-only setup with one that is ABS AND difflock. This harness terminates at the left quarter. To be true plug and play you will also need a complete floor wiring harness. (big money). You can build a 5 wire harness of your own and run it along the existing floor harness. This is what I did. It is 14 feet long and is terminated on the front end with OEM harness repair splices that fit into the un-used cavities of the floor wire harness side of the connector that mates the floor harness to the cowl harness.
