Unknown Connector

[Darkstar72]

I was just going over the car and found a connector that is just hanging out not connected to anything. It’s a weather tight connector with 4 pins that branches off the harness on the drivers side rear of the manifold. Wires are colored pink/black tracer, gray, brown, and black. I can’t locate a sensor or any other item this thing would have gone to.

Car starts, runs, drives with no lights on the dash but I’m assuming Buick put this connector there for a reason.

What is this supposed to go to?

Egr valve

If you're using Erics chip he disables the EGR via his chip.

Ah. OK. It does have TT chip. So tuck it away and forget about it just like the dude from Silence of the Lambs. Mystery solved!

Thanks!!
