i got a male side 4-wire O2 plug in my hand. its yours.

as for the vacuums... i had a Z6 in my EK at one point... im pretty sure i did this:

TB vac = blocked off.

big nipple on back of IM = brake booster
little nipple on back of IM = EVAP purge plug/valve/sensor/thing
big nipple on front on IM = went to black box on back of block (i think)
little nipple on front of IM = fuel press. reg.

that should do it i think... lmk if u got any other probs... and PM me about getting this O2 harness.
