Good Thread!
I just changed the fog to a white reversing lamp using the Car Solutions white lamp shown in this Thread. However I have yet to hook it to the reversing switch.
I ran my own cable from front to rear to use the oem fog lamp switch on the dashboard for upfront fogs.
Next step is track down the reversing switch and tie my cable into it. I am sure I will be able to do it but it appears that removal of the transmission tunnel must happen for access. I did spot a switch from below but it looks like a pressure switch. Is that what I should be looking for?
I also got into the rear indicator pods and found that a hollow shaft pod is needed to keep the oem look to replace the reflectors with red led lamps.
