...Making your own '730 harness? Anyone know where to get the sensor "Connectors" or clips at a reasonable price? NAPA wants an arm and a leg for some of them.

 

The GM parts counter may want even more for some, less for others. You might have some luck at a parts store that sells the full line of Standard Motor Products, who has available about every connector used on the vehicle.

Another option is a used harness.

 

Yeah, I think I may just have to try to establish a relatinship with a local dealership and go from there.

I was looking into used harnesses, but have found that either the intake's aren't sold with the harnesses, or the one's that are often carry is disclaimer "unknown condition," etc. New one's range from $250 - $700 ( ) and this isn't for a vehicle that ever came with TPI anyway, so I figured - custom lengths = customer harness, and what's better than learning to Do-It-Yer'self. Ok, ok, I'm just cheap.....

 

I've grabbed connectors from the wrecking yard on multiple occassions, just have to buy the actual terminals, which are much cheaper than the connectors themselves.

If you want it all clean and new, then this won't be for you, but if building your own harness, you might want more or less terminals per connector than stock had, so wrecking yard is a valuable source for that stuff.
