now i feel stupid, i just was in the garage looking some stuff over and realized it supplies the vacuum for the heater controls.

eagleuh1

you got a vacuum line in your wiring loom?

yeah it hooks up on one end right at the back of the intake, and then i realized the other end, whick is by the pcm hooks up to a vacuum line to the heater controls. i should have known this my 95 z28 has the same hoses there but my 68 has mechanical controls not vacuum.

i think...... 99 but not really sure. it has an egr connecter, so im guessing 99 or 2000 cus if memory serves 01 and up had no egr? but then there is another connecter on top of the pass side coil pacs that i have no clue where it goes and cant find anything to plug it into. its this one in the photo



it has 3 wires? and its hard to see in this picture but the colors are blue w/ a white stripe-yellow w/ a black stripe- and green

almost looks like the plug for the map sensor.

nope, i think its for the EGR solinoid that used to sit infront of the pass head.

deff not the egr plug/ the egr plug is a like a 90 deg plug. might be either the map or cam sensor plug.

where is the cam sensor and where is the map sensor? if i can find those i'll see if they are already plugged in.

and yeah, i figured out the egr one, it has 5 wires and is all the way up by the throttle body.

SICMARO

map is on the rear of the intake just about the brake booster hose. the cam sensor is next to the oil pressure sensor on the rear of the block.

could be the AC High Pressure Sensor.. ? No sure of the color.. as I didn't use mine and deleted it.

yeah i found those two and i already have those plugged in. and i was wrong about the colors (thinkin of a diff conn.) its red-pink-brown w/ white stripe

it looka lika dis

ac should be a round plug w/ 3 wires. thats the pass side of the engine?

i looked at a stock 2002 z28 today and did not see this plug. and yeah the ac plug is round i know wich one that is. so i have to guess this is a 99-2000 only plug since its not on the 02 car i llooked at. i wonder if there is anyhting else that was done away with along with the egr?
