My truck is a 2007 Tacoma access cab 4X4 V6. The only option I have is the convenience package which includes power windows/door locks/mirrors, remote keyless entry, cruise control, sliding rear window with privacy glass. I ordered a set of fog lights from Advance Store, about $190 for the two lights. After removing the factory plugs the lights I bought plugged in just like the factory lights. I had crawled in under a Tacoma with factory installed fog lights to look. I had seen a coiled wire with plug taped under the fender well of my truck This factory installed wiring harness had a plug on the end exactly like the one on the factory installed fog lights on the truck I had looked at. The plug on this "factory wiring kit" plugged into the fog lights I had just installed. My next search was for a factory switch. I ordered one from eBay ($18.95) and when it arrived I found it was for a older model truck. I went to my local dealer and ask if a stock switch was available for the fog lights. He told me no but after I insisted he looked at his Tacoma parts list he found one and I ask for the stock number. The Toyota stock number is 84160 04010, my local dealer sells this switch for $54.95. I looked on line and found a on line listing for Toyota Parts. Address is http://www.toyota-parts-dealer.com/
I plugged in the part number and found the switch available for $35.48 plus approximately $10. No sales tax since it is coming from Virginia to Tennessee. Total time for installing the fog lights was about 10 -15 minutes. I removed one of the blanks on the dash and the wiring is there for the switch I ordered. When it arrived it took me longer to remove the plug from the dash than it did to install the switch. Total time involved was about 30 mintes.
