Default need help how to remove this!!!!!

I just took off my vlave covers on my 90' so to do that I had to loosen the ac bracket. I have a couple of questions

1. what is the black box with tubes connected, and 2 wire harnesses in it, brace between AC and smog pump? I want to remove it, and the tubes. what about the wire plugs?
2. If I can delete it do I reuse the little black braces?
3. I am thinking of removing AC rightaway, because I usually run just the fan for venting heat. How hard is it on these cars?


SOOOO much clutter in this thing
thanks guys

1. what is the black box with tubes connected, and 2 wire harnesses in it, brace between AC and smog pump? I want to remove it, and the tubes. what about the wire plugs? Those are the smog control valves that are housed within...they divert the smog pump air in different direction when the silenoids are energized.
2. If I can delete it do I reuse the little black braces? If you remove the smog crap you'll free up a bunch of room/clutter in the engine bay area....you can toss the brackets if you like.....you'll have to block off all the areas in the exaust where the smog taps in though....a trouble code possibly be thrown if deleted.
3. I am thinking of removing AC rightaway, because I usually run just the fan for venting heat. How hard is it on these cars?
The bracket that blocks you from getting the valve cover off easily can be cut back for clearance...the mod just takes a few minutes with the bracket removed from the car. This way you can keep your AC and not have to pull your hair out when it is time to remove the valve cover in the future You can pick up a A/C delete pulley for a ~$100 If the system still has freon in it you should take it to have it recovered before you tear it apart. The whole A/C system just unbolts but the evaporator housing will be a little trouble to remove because of the tight clearances. You'll want to reinstall the evaporator housing if your going to run your fan down the road. If you don't want your old running leak free A/C compressor send it to me....I'll happily pay the shipping.

ok thanks, I will let you know on the ac when I get there, so I don't have to do anything with those 2 plugs but unplug them from the diverter box?

also on my intake base I have an egr block off on top, but do I need one for the side when I remove the tube?
thanks
