Yep, the seller, has not returned my calls. No doubt I'd have to pay return shipping and then pay more for the DEL model, I'm just going to mount a switch inside the cargo compartment just next to the hot water compartment.... or use the existing (red-green-blue) wiring from the for a new switch on the control panel.

Your old switch will operate the LP side just fine. Just cap off that white wire. The switch you just posted is the dsi LP switch with NO 120 switch. ALL your original 120 side switch did was send a 12 volt pos signal to the orange wire to close the 120 12 volt operated relay. Just connect the BLACK 120 HOT wire to the BLACK on the new heater. Connect the large WHITE(neutral) wire to the WHIT Neutral on the new heater. Ground lug is obvious. You will be bypassing the relay assbly. Doug

Your NEW unit. Remove the BLACK wire that is stripped. Then remove the BLACK wire with the spade terminal on the relay and strip to wire nut to the 120 feed wire. Doug

Or if you wanted to continue to use the inside 12 vdc switch as is, buy a relay with a 12 vdc coil and contacts rated to handle the 120 vac and rated current of the heating element, mount it at the water heater, and wire it in the same as if it came with one.

BRAIN FART BIG TIME. Just remove the OLD relay and relay container and install on new W/H. Simple and no need for additional parts. This way your inside 120 and LP switches will function. Doug
