All vacuum accessories need to go on the intake manifold because pre-throttle body, you have atmospheric pressure. The only slight alteration to my picture below is that the wastegate is supposed to be connected to the compressor housing via vac port.

i was also told to wire a injector resistor box from an older civic (5 wires ; 4 red black tracer and 1 yellow black tracer) with a distributor harness ( 8 wire ) to another harness that is near the brake booster ( behind strut tower ) also 8 wires harness all wires yellow black tracer ... i was given a picture and im wonderin if it matters which ones go where ... the 8 wire harness from the vehicle (yellow black tracer) plugs into dummy plug which inside is a loop that joins all yellow black tracer wires together??

i know you must be tired of answering my questions but i just had one more kinda stupid one .... for the boost guage setup ... should i 't' into the the line from the booster after the backflow valve ? or should i go closer to the BOV or wastegate vac. line or elsewhere ?? ..

I ran my boost gauge off a nipple on the manifold, but if you have extra room on your vac manifold, you can put it there too. If you dont have a vac manifold and plan to "T" everything in, just toss the boost gauge in on the vac hose to the brake booster.

My advice to you: Invest the $40 and get a vac manifold

well now everything is installed and runing. i got upto 5psi of boost ... not great i know but my idle when warm is really low and i think im runin rich cuz i got black smoke @ idle .. spools up pretty good ive adjusted my bov and i think my wastegate needs some adjustin (no prob.) but my low idle has got me a bit stumped .. my comp has been chipped as per advisment of a friend .. got any ideas on the low idle @ idle . . ?

You prolly need to get your car tuned..if it has been chipped that is only a rough guess of what you car should be doing.

I am assuming you are on a basemap since you said it was chipped..if your not even on a basemap than you def need to get it tuned..

i am on a basemap .. i've been playin around with the iac abit and i think thats where my problems are ... so most likely the guy who chipped my comp. is the guy to fix this prob. right ..? the only other thing is .. my wastegate seems to open too soon ..don't know what normal psi usually wastegates operate on but mine seems to open with about 2-5 psi ..giving me no real boost and a slow spool up.. i was thinkin of goin with a grainger valve (pressure releif valve) .. what's you take on those ..cuz i tried adjustin the wastegate but no real diffrence acheived .. it's weird cuz at one point i was seein about 7 psi on my guage but now i get nothin -0- sometimes it goes to 2 on WOT
