Thanks to this Forum, I did the Fog Light "ON" Anytime Mod without problems.
I then decided to change the switch to one that would be lighted when I turned them on.... I purchased the Toyota Lighted switch #00550-35976 ...... problem is.... it has thee prongs on the back.
I took the four wires out of the OEM original switch harness and found that:
One wire is power, one wire goes to the RELAY, one wire is (the white with black stripe is the ground) and the other wire (green with a white stripe) is also a ground.
I have attempted just about every which way to connect the wires to a tree prong switch and can not seem to get them to work consistently. When I connect both grounds together the lights are always on regardless of the position of the three prong switch..it appears the thee prong Toyota switch will not work with the 2010 Toyota four wire .... for that reason... and from info on this forum... I think I'm just going to put a remote little LED light wired to go ON when the lights are on.....
My problem now is, I don't remember the order of the wires to put back on the original switch.. I pulled the plug apart and now have the wires with the male plugs (four of them) and think I'm going to have to use the Original switch with the LED lights.
Does anyone know the order of wires...white,, green, green with stripe, blue? and to which wire I would connect the LED?
Thanks for your help.
