water heater wiring need help

I have a Suburban Model SW12DE w/both gas and electric heating. I want to move the outside (at the heater) rocker switch for the electric element to a more convenient inside switch. I have suburban's relay and the inside switch that controls both gas and electric. Question: Will the red signal light on the inside switch be used at all w/the electric heating element? I understand electric circuits pretty well, but where shall I ground the 12-volt signal wire exiting the relay? I will have to bench test the relay to determine which terminals are for 12 or 110 volts, unless someone can offer me a diagram? Thanks for whatever help you can offer ! :@

shastagary: Thank You! for the link to the manual. Just what I needed.

SoundGuy: A very good solution! Thank You.

I will go w/SoundGuy's solution so I don't need to involve the module that is part of the factory wiring.

You forum folks are the greatest. Thanks!:B

the suburban 110v switch and relay are used on the sw12del model.
the wiring is shown on page 6 here manual
i did as soundguy did and installed a switch with pilot light connected to the outlet my water is plugged into that works great for me.

SoundGuy has the easiest solution I have seen posted. Nice job!

Leave the water heater as it is, with the electric heating element switch turned on, and simply add a switch in the 120 vac feed to the WH. I chose a switch with built in light and mounted it on a wall where it was easy to reach, easy to see when the on light was illuminated.
