By the way, I also recommend attaching your wastegate/boost controller there too, INSTEAD of at the turbo outlet to prevent boost creep, pressure loss, and you haave better control there.
Can you draw me a picture of what you mean? Ive had to replace the motor and I believe that the guy who owned it before me did this. BUT i dont know how it works like that. Everybody else is telling me to hook my MBC to the turbo nipple and wastegate nipple. Thanks for the help in advance.
88 mx6 turbo/5 speed ,HKS boost control,HKS turbo timer,Blitz bov,turbo back 2.5 exhaust,Borla Muffler,Ractive air filter(mushroom shaped) turbo,chip mod. Only 10lbs for now.

You don't want your boost signal coming from a vacuum source ie; anything behind the throttle body. Also, this is for boost gauge install, not boost controller. Everyone is correct in telling you how to hook up your MBC.
SEARCH SEARCH SEARCH...this is not a new concept and you're not new here.

can you tell me why the guy i bought it from had a hose going from the turbo nipple to the wastegate nipple with a T going to one side of the MBC? There has to be a reason for this....it worked is the weird thing.

probably a bleeder valve kind of thing, with no adjustments needed.
got pics?
I can get some but its really just like i tried to explain. The compressor side nipple has a hose that connects to the wastegate with a T in the middle that i believe was connected to one side of the MBC. The other side of the MBC was hooked up to the valve cover hose with a T.

all you need is the boost source from the compressor cover to the ball side of the MBC, then the spring side of the MBC to the wastegate.
Whoever hooked up the MBC was retarded. There's an in and out on a MBC, there is no third connection. All that did was bypass the wastegate all together...unless there was a bleeder valve that you could open and close on the "T".
As for your gauge, use the top vacuum line in your pic.
Actually if you get a Forge under bonnet bleed valve: Forge Motorsport | Alloy Fabrication
Block off the lower fitting and hook it up like pictured above.
It will work better then the ball and spring MBC that don't seem to work very well with the small factory waste gate. They sit inline with the waste gate and hold off boost with a ball bearing, a spring and small bleeder whole, at the set boost the ball bearing gets pushed and boost pressure opens the waste gate... unfortunately they never seem to hold the preset boost very high in the power band.
You can install the controller in the dash.
The best set up would be to use boost from the charge pipe before the throttle body instead of from the turbo housing to regulate the waste gate*.
------------
I recommend:
Block off the waste gate nipple on the turbo housing.
Thread or weld a fitting to the charge pipe near the brake master, run a hose from it to the waste gate actuator, T that hose off (near the brake master/fire wall) and run a hose into the dash to the bleed controller and out to the PCV pipe like pictured.
-You can change/increase the sensitivity or control of the bleed controller by adding reducers to the waste gate line before and after the T (none in the controller lines). Mig welder .035" welding tips work great.
This give you full control over the amount of air going to the waste gate actuator, makes the base or stock activation of the waste gate more efficient or even to intake manifold pressure and vice versa:* an 8lbs waste gate that opens at 8lbs after the intercooler and is more likely to achieve 8lbs boost in the intake manifold then if it opened at 8lbs boost at the turbo before the intercooler and pipes giving 7lbs boost at the intake manifold. This 1lbs gain in manifold boost as a base for the waste gate makes it more efficient at holding the average 15lbs boost people look for from the stock turbo and a chip .
