Phillips Industries premium 3-In-1 and 4-In-1 electrical and air combination assemblies with QCP trailer side connections have been improved to reduce fatigue and strain on the plug and seven-way electrical cable.
The trailer side lead on the seven-way electrical cable now extends out an additional six inches, and the spiral wrap on the same side is reduced by six inches, creating more slack on the seven-way cable. This change relieves strain placed on the cable lead and coupled seven-way electrical connection due to pull from the weight of the combination assembly experienced on some trailer applications.
