This came off a 6x4 with 151 hours. It was used as a snowplow actuator, but the snowplow was removed because of low use. Even though it was used as for a snowplow, it is a one for one fit as a power lift for a box. I've done it. Everything is there to complete the installation, relays, switch, connectors and wiring. The only connections to be made are to the battery + and a good ground. $675 and I'll pay the shipping.
