my first ls swap 1996 2 door Tahoe 4wd 385 Stroker to LQ4 cam headers **pics**

Is it not in the fuel injection hole? Either way, pull the intake and go get it. A piece of duct tape wadded up and taped on a stick can retrieve it.

nice always wanted a 2 door blazer/tahoe. Gonna put a 5.3 in a 91 awd olds bravada so ill keep track of how this swap goes

the one grey harness connector with the slide clip looks like my transmission connector.

The two in the pic together look like the two that plug into your original throttle body. One is the TPS, and I'm not sure on the other.

Those aren't TB plugs, the 2003-07 DBW throttle body only has one plug on it.
Hard to tell out of context like that, but it looks like the knock sensor harness plug and MAP lug to me.

That big grey connector in your last pic goes to the shift position detector for the gauges on the new truck you dont need it.

not sure how you got it together with the shorter bolts but yes, pull it apart and put the correct bolts in it.

put a tape measure on it, what diameter? Could be an output shaft oring if it's large enough.
