I need to replace the front side marker lamp (passenger side). I found a place online to buy the part. Does the replacement part just snap in? or are there some tricks to get it in right?

 

Follow this link. It shows step by step on how to do it. http://mywebpages.comcast.net/rx300h...de_markers.htm

 

You go through the tirewell wall. You have to remove the retainers on the wall, then flip open the wall and get to the light from inside. There is one nut you remove and then is slides out. Installation is obviously the reverse. It's a fairly easy to do task.
