worked great to swap a ls2 silver blade body onto an 8.1 engine
if you are looking to upgrade your stock poor flowing 99-02 8.1 throttle body this harness is what you need. plugs right into a 6,0 vette silver blade intake but you will need to swap the 2 pins on the actuator plug for throttle body to function. stock intake boot will fit but trimming the fan shroud and replacing factory intake is recommend for performance applications. long tube headers with good wires in addition to this throttle body upgrade has increased my mpgs and power so far without a tune. im planning on installing a raylar intake and cleaning up my head ports soon to hit my power numbers. sound increase with all this done on stock system is minimal

OK if it worked but QC is not good
I work for a harness manufacturer and I'm an engineer. this adapter threw codes if the harness is jiggled. I depinned what I could and it is clear to me that whoever crimped the GT150 terminals on the 6 way throttle body plug failed to do the job with the right die set or wire strip length. This would NEVER pass my own QC let alone my customers. I bought all new materials and will build this myself with quality parts and tools. This thing is going in the scrap bin the only useful part of it is to see the schematic. As a bonus, it is a lot of fun to go into limp mode in the middle of traffic because some crappy terminals and tools were used.

Works great
Works great. Used to put a ls2 throttle body on a lq9. If you have a 99-02 truck you have to swap the yellow and black pins for the actuator.
