HELP!!! EST PLUG ON 1989 GTA...LOCATION?

Hi all,

I know this is sorta stupid, but I can't find the tan/black EST wire to set the timing on my 1989 GTA. I checked my brothers 1990 Camaro, also not visible. What the heck did they do with it when they switched harness design in 1989??? Thanks in advance.

Same place its always been. Passenger side, near the blower motor for the AC/Heater. I just did this last weekend on my 89 GTA.

I tore that entire loom apart...no plug. But I'll go check again.

No need to tear the loom apart.
The connector is there. Unless someone has modified the car or harness.

Well...something must be amiss then. I can find it easy on my brothers other car (87 IROC), but its not in the same place on this car. It should be sitting out of the loom, exposed, correct?

Found it...on mine and my brothers 90 Camaro, its on the secondary harness, the one that runs to the fans and emissions canister solenoid. But now I have other issues.
