I am doing a single turbo conversion and want to know where I need to connect the vacuum line to from the unit on the side of the UIM. I believe it is called the double throttle control actuator.
Normally this would have been connect somewhere via a solenoid but these have all gone as part of my single conversion.
Please can someone tell me where I should connect it and if I need to put a one way valve in the line for it? If so is it working under vaccum or pressure?

Thank you

Get rid of it all together

 

Really??!

Just the vac unit? and leave the butterflys in place?? I presume they will just remain open constantly?
Exactly what do these do? Sounds a bit dodgy to me!!

Cheers

No get rid of the butterflys as well.

Sweet dude.. Thanks for that link! I'll get on that tomorrow! I take it I should leave the bit below on with the electrcial plug on it which I assume is the idle control valve?

You can eliminate the IAC also. I eliminated mine, some of the old heads can probably tell you the pros and cons of this. Someone makes a block off plate for the double throttle or you can do the bolt and nut thing or weld the hole shut.
