Throttle bodies, TPS's and Idle Control

[boostedb5audi]

My OEM throttle body is too small/restrictive for my intended power levels.  I purchased an OBD1 VR6 TB which has a TPS on it,  but I can't find any provision for idle control.  what did these TB's use for idle control?

Also,  does anyone know where you could buy harness side connectors for the TPS found on the OBD1 VR6 Throttle body?

Have you looked at R32 TB's?  I know some folks using Dodge Durango TB's.
