everything but the plenum back on, with new grommets/gaskets, etc. new injector connectors are visible. these can be unplugged with the plenum and everything else in place, if wanting to test for a misfiring injector, and will also allow swapping the connector to a different injector to help diagnose a non-firing injector, also with everything in place - no more trying to unclip the piece of shit factory connector with no space available to get a small pick/screwdriver to release the wire clip
