We are trying to get idle control working on a 99 Miata with an MSLabs MS2 enhanced PnP. There is currently no power at the IAC. The ECU is second hand and we have no documentation. There are 7 wires that are unterminated and not a part of the PnP harness. 1 of them (yellow wire) is connected to 5V and that's it. Are we missing something here?
