Here's my take on the parts list
I do not have the Sport model, just a standard 01 ETC withOUT the fog-light kit.
I purchased two things from the dealer...
1) Headlight switch w/ fog - #56021675 - $59. 20
(BTW, they asked me if I had a dome light and I do)
2) Mini-relay for under the hood - #4671168 - $10. 35
That's it.
Out of curiousity, I asked what the complete "fog light kit" would cost, I was quoted $169. 00 and change. This would include the switches and relay I purchased above, plus the lights and bracket, the wiring harness which plugs into the open plug under the front crossbeam and goes to each light and new plastic bumper inserts which have bigger cutouts for the lights.
Since I plan on making my own bracket and have no problem cutting the existing plastic hole bigger, I only purchased what I needed.
Also, I know there have been group purchases of the Catz MSC's in the past... say back in 01 or early 02 from what I have read in some other threads. Not sure what kind of deal was had back then or what could be had currently. When I checked the web for prices on the MSC's... I found them anywhere from about $160 to $210. Then some added shipping... one wanted over $25 for shipping... whatEVER!!!
Before purchasing any parts, make sure you have the factory open-ended plug under the front crossmember just under the radiator and behind the front bumper. The other end will be in the dash, right beside the main plug for your light switch. The back of both light switches (the one with the fog function and the one without) are <b>exactly</b> the same. However, the main connector... with about 20 wires on it is all you need connected if you do not have fogs. The smaller plug with only two (or 3) wires is the plug used for fogs. This connector was originally plugged into the back of my switch even though I did NOT have fogs. I unplugged it months ago to confirm what it was for and all the interior and exterior lights continued to operate normally.
If you have this scenario on your truck, the two parts mentioned above will probably be all you need from the dealer. If you don't have one or both of these plugs, you probably do NOT have the factory wiring in place but I believe this is rare.
Then all you need is the lights of your choice and a bracket. You'll also have to create your own wiring "harness" to connect the lights to the plug under the crossmember. One dealer said he had this harness for around $35. The other couldn't find it.
BTW, I have two Dodge dealers in town and the prices on the parts quoted above varied by about 2-3%. YMMV.
