Although electronic climate control is not standard with the Hurricane system, you can turn your Hurricane into a Category 5 rock-and-roll experience with this electronic climate-control add-on from Old Air Products. The standard Hurricane system is cable-operated. The electronic climate-control system turns your cable-operated Hurricane into an easy-to-use touch control. Instead of a cable-operated hot-water valve and manual shutoff, you get an electrically operated two-stage valve that completely closes off hot-water flow whenever the heater is switched off. No manual shutoff, no cables-a drive-by-wire climate-control system you're going to like.

The electronic climate-control harness has two similar multiplex plugs-one activates the hot water valve, the other operates an air door for defrost/heat. Don't confuse the two. | 
The master control is easy to install because plug size and configuration is specific. It's virtually impossible to get it backwards. Blue wires are for instrument lighting-a light-emitting diode. |
This system employs a super-smooth, three-speed fan switch, as well as an air control that enables you to switch from heat to defrost. When you need cold air, just touch the A/C button for prompt compressor-clutch engagement.
To install the electronic climate-control option, you must first swap defroster air-door assemblies. Remove the cable-operated air-door assembly via two screws. The electronic climate-control defroster air-door assembly is solenoid-operated and attaches via the same two screws found with the cable-operated assembly. | 
Earlier, we cited the difference between cable control and electronic control. On the left is the cable control and manual shut-off. On the right is the electronic shut-off valve, which does the work of both with a slider control. | 
Installed, the electronic hot-water valve looks like this. Keep the valve away from hot exhaust manifolds and headers. Route the wiring as shown, away from hot surfaces. We came through one of the heater-hose firewall passages with a rubber grommet for safety. Refrigeration lines will tuck nicely behind this valve with 90-degree fittings. |
