DBW Throttle Body differences What options are out there for a Gen III style drive by wire throttle body with 8 wire connector?
Is the old three bolt the only thing compatible?
I know that a lot of later ones are 6 wire connector / 4 bolt units that can be adapted with an aftermarket convertor.
What are people who have 2004 - 2007 DBW systems doing when they want to upgrade from stock top ends to L92 / LS3 heads? Or when they simply want something more than the 78mm stock TB ?

The pedals have some variation... I noticed the silverados are more compact and the Yukons are HYUGE.... Try to get the harness, module, and pedal from the same vehicle though... LKQ all in price should be around 60 bucks for the three
