The super-poor can have them too!
If this has been done before, I am not aware of it.
I got bored after work and this is what I came up with.
I had a plug laying around that was for an illuminated switch.
I removed the orange #9 pin and spliced it into the orange wire on the heater control switch pigtail. Ran the wire across to the switch where I placed it in the open #9 slot on the plug.
I still don't have any good bulbs yet, but I did check the strip across the top and confirmed 12V at the switch.
So, all in all, it took about 45 minutes, 30" of wire, 2 wire crimps and a Diet Dew to rig this up. It's 90 degrees in the shade so I don't know why this couldn't have waited.
Also, completely unrelated, as I did this weeks ago but I got a pic of it finally:
This is how you rig up your car if you only have one working key and do not want to pay more than $4 for another key.
