Yes! Me too!

Also, I put that connector back on BEFORE I bolt the plenum back down. That little bit of extra room allows me to gently maneuver and position that connector in place: actually feel the pins sliding into place before the connector bottoms out. Then the set screw/bolt only secures the connector from coming off: that way it never is used to wrench the connector over the pins (is when pins get folded/bent).

....especially for those first timers pulling the plenum:

Two of the best suggestions I learned from this board, regarding plenum pulls: 1) is prepping the (new) plenum gasket before installing it, and
2) installing a plug in the coolant port of the driver's side injector housing, blocking off coolant to the throttle body.

Prepping the gasket amounts to using some 3M adhesive on/around the injector housing coolant port only (a thin layer) to keep the gasket from squirming away from the coolant port. (Less of a problem since Jerry's Gaskets started providing those gaskets!) And, second, I found that spraying the plenum side (only) of the gasket with a silicone spray (ACE Hardware or the like) facilitates future removal of the plenum.

Once the bolts are removed, I can slide a putty knife along the entire edge of both sides of the plenum and the gasket remains attached to the injector housing and intact. (I've been able to reuse a gasket for a couple of additional plenum pulls. However, I keep new gaskets handy "just in case".)

Plugging the coolant port in the injector housing that feeds coolant to the throttle body saves most of an hour when it comes to pulling the plenum. Unless you're in the habit of driving your Z in freezing or sub-freezing weather, you will never miss it. And, doing so - not having to fuss with coolant, and with the help of a pneumatic ratchet to remove the bolts - a plenum pull and re-installation is a breeze!
