Anyone know where this connector plugs into? It's on the same group of wires as the large blue connector behind the ecu.

 

Diagnostic connector for the cooling system. It doesn't plug into anything.

 

thanks. one more in the engine bay... it is where the a/c and power steering pumps are located. looking at the white one that is disconnected.

 

i just hooked up my ecu and wiring the last 2 days had the same issues as you with the ecu plug

and there should be another another plug for that white connector to fit into, somewhere off the main harness

edit: or is that your A/C one?

 

a/c is a large black and yellow connector. i still cannot find where the white one goes.

It's hard to see the connector in that picture but if remember right on that side of the engine there are white connectors for the oil level sending unit on the oil pan, the knock sensor on the side of the block, and I think the oil temp sensor on the block which is under the oil pressure sending unit.
