Customer Question

I have an 04 Seville that I replaced the heater core on. There are a couple wire couplers I don't seem to be able to locate there counter parts . The one is a big 40 some pin plug with a big clamp that swings around the back side of the plug to latch it.
It splits off from the radio harness and as big as it is I a can't seem to find its counterpart. The other one is a little twenty wire plug, purple, black white, orange , ground, black white, green white, and brown white On the passenger side.

Do you have anything that doesn't work? It is not uncommon to have connectors that aren't plugged in. The one looks like it might plug into the HVAC module.
