Is the 1.0 now obsolete? Looks like the 2.0 is new and improved.

 

That is correct.

 

does the 2.0 need to be modified to work w/ a tbss t-body or is it plug and play?

 

Wondering this myself.

 

The 2.0 will only work with the car style 90mm TB. The 2.1(coming soon) will work with either.

 

What options are there for putting a larger throttle body on a DBW 02 truck, with the 2 wire connector? I'd like to run a ls6 intake.

The site above mentions "a straight adaptor harness is supposedly all that is needed to make these work" however does not mention where such a harness would be obtained, or whether it has been tested to work on an actual vehicle.

 

The "LS6" intake is still 78mm. You might want a TBSS intake for 90mm. Contact Speartech or google "LS2 adapter harness".

 

thank you very much for the information. Glad to see someone knowledgeable answering questions here.

 

is there no longer the pink wire to connect?

 

That is the primary visible difference. It's plug n play.
