Default LS1 to LS6 swap HELP

I have a 98 LS1 that I am putting an 04 LS6 with a FAST intake with a 91cm throttle body on it. The wiring harness for the LS1 throttle body doesn't match up with the LS 6 FAST intake throttle body. The LS1 has a 2 pin connector and the LS 6 has a 6 pin I believe. Any way to work around this without going back to the LS1 throttle body?? I was told I needed an "LS2 to LS1 throttle body conversion harness" Anybody have any idea where I can get one of these?? Thanks in advance!!!

Wow, a 3 foot diameter throttle body......that should be free flowing.

If I understand correctly, the new engine (LS6) has a FAST intake, with a 90mm throttle body, and you are installing it into a 98. You just need an adapter harness to convert from the LS1 throttle body, to the LS2.

Thanks a lot for interpreting my question correctly and giving me the solution. I appreciate the help. I know the old (C2) vette's pretty well, but just bought this 98 to have some fun on the track with, and don't know a lot (but learning fast) about the "new" vette's... Thanks again

PS. Also glad you were smart enough to realize I didn't have a 3 ft. diam. throttle body like some folks.
