Ah so. Well I never took the housing out of my 94 when I had it (RIP

) But it should be pretty straight forward. Probably two bolts holding it on the top and two more on the bottom. There could be one bolt that mounts horizontally on the bottom. Thats how it is in the 98-02.
As far as taking off the bumper, also straight forward. Gromets in the wheel wells and gromets/clips underneath. They probably either pull straight out (you may need some pliers if they're stuck) or some screw out before you can pull it the rest of the way. If you don't feel like taking off all the clips on the bottom, you can just kinda let the bumper hang off the front of the car. Thats what I do.
When putting it all back together, try to get everything to fit as tight as possible before putting clips/screws back. Most likely once you take it all off, it won't fit back exactly as it came off, but you can toy with it to find out.
First time I swapped out headlights it took me about 30 min for the first one, mainly cause there is a screw in a very inconvenient spot. But after the first time it only takes me about 15 minutes to get the bumper off and the headlights out.
OH WAIT! Please remember to unhook or take out your bulbs before you try to yank out the housings.
Good luck mang
