Default Please help! Unknown connector.

I cannot find anywhere this connects to
  1. It is orange and black
  2. 2 post connector
  3. located on drivers side
  4. comes out of the harness shown in the pick
  5. not a very long wire
  6. nothing I can see screwed into block

I am at a loss. I have looked at some diagrams but don't see it pictured but I admittedly not good at reading them. Let me know what additional details and pics are needed.

Please help if you can.

Thanks!
Wade

Purely a WAG of sorts but maybe the MAT sensor to the jumper on an L98 - might make sense for your '90. I believe on a '90 you've got the MAT then a short jumper to the connector in a loom near where your snapshot seems to be.

If my WAG were correct this "jumper" would connect to a weather-pack near where you snapshot seems directed.

This is a 90. The wire colors are orange and black. Here is the pic of the connector.

The MAF is plugged into the bottom of the plenum towards the back correct? I have that hooked up. So I am looking for the other end of the MAF wire to plug the unknown connector to?
