does anybody have or have a link to the DBW TB wiring?
03+ trucks
or
00+ tahoes



thanks

 

bumpy.
can anybody put up a link or whatever for a wiring diagram for the electronic throttle bodies?

thanks a bunch.

The pre 03 is a different setup than 03-05. Then there are some changes again in 06(and 07 Classic), and the NNBS 07 and up is another new setup. What do you need to know?

 

thanks for the response bro.
im attempting/researching using a truck/tahoe dbw throttle body on a v6 fbody.
99+ v6's also have dbw but the tb is only 65mm...im looking for at least a 78, more if i can get it.
the v6 unit cant be punched out that far do to the gears/shaft and electronics clearancing in the throat (yeah i tried...LOL)
so yr model is really unimportant to me as long as the throat/blade are larger.
thanks mang!
much appreciated.

 

Looking at the description and operation for the F-body V6 throttle system, I would say that with respect to the TB itself, the 03 - 06 truck 78mm is the closest match. In both systems the 2 sensor signals move in the same direction, increasing as the throttle opens. Both use 8 wires to the TB. Not sure if the resistance of the TP sensors will match close enough though.

Here are the pinouts for a 2004 truck TB connector. Wire colors for the circuits appear to be similar. As long as the resistance is similar it could work. You may have to swap the TPS1 and TPS2 circuits, possibly not.

 

Here is the 1999 V6 TAC system:

 

And here is a 2004 truck TAC system:

 

Looking at those schematics, I get the feeling that each TP sensor on the V6 TB will have a unique overall resistance, whereas on the truck TBs, both sensors have similar resistance values. i.e. each system employs a different strategy for fault detection.

 

thank you sir.
mucho appreciated.
helps a ton.

i can remove the Tac and even the motor from the v6...thats simple enough.
wonder if i could just swap it into the truck tb..hmmm

thank you again.

 

Hey im trying to do a ls swap in my 2000 4.3 single cab silverado with a 08-13 escalade 6.2l with the 6l80e and I can’t find the adapter to plug into this Interior connector for my dbw for nothing. Do anyone know where can I find it at
