A6 to Z6 swap: fast idle plug?

Swapping an obd1 ecu and D16z6 into the 89 RT4wd, the A6 motor has a fast idle valve with an electrical connector coming off of it.

The Z6 fast idle valve has no electrical connector or wires at all. I'm assuming the ecu doesn't need a signal from it, and it won't need one.

So do I just leave the plug on the harness unplugged? I'm going to call Rywire tomorrow (that's where i got my ECU conversion harness), but i thought maybe someone here would know.

THANKS!

    yeah, I'm aware of that, I'm using the Rywire obd0 to obd1 jumper harness to convert to obd1.

    Correct, there are no connectors on the FITV on the z6. It used a thermo valve that reacts to the temperature of the coolant to open and close. On both of my z6's I have blocked off the FITV because they were malfunctioning. The only side effect was that it took a little longer for the engine to reach normal operating temperature during the winter. Just leave it unplugged.
