The bottom line is that it's not going to be easy to get backlite and a switch on indicator.
I posted a thorough reply including several links. It was pending when I left the page on June 24. I'm guessing it was never approved. In a nutshell I cannot locate a switch that has a lamp between terminal 2 and 7 which would come on when the key was on and a second lamp between terminal 3 and 7 that would be on when the switch is on.
The factory block only has 3 wires. The default pilot light on most switches runs between +8 and -7 ground. The lamp when the switch is on is between +3 and -7. I had Delphi female plugs and installed a female plug on terminal 8 and ran the wire to the "A" block using an SAE connector. I used a Carling V1D2 Contura switch from DigiKey.
The easier solution would be to abandon the factory plug and purchase rocker switches with labels and jumpers from Amazon like Jason originally posted. Pull up to 20 amps from the switched "A" circuit under the dash. I have a video on YouTube called Wildcat XX Accessory Wiring that explains the basic layout and has a link to the wiring diagrams.
