MAT sensor has about an 10" pigtail that goes between sensor and connector at main harness on firewall.

This is completely different that the separate pigtail for your IAC/TPS/MAF & AIR/ALT connectors.

IIRC, There is a 2-prong connector for the AIR router. If yours doesn't have the AIR pump system anymore, that's your extra plug.

Can't figure out what you mean by the other question. But the ESC and tack wires are also on the firewall.

Plus, oil pressure/sender and your MAT connection.

O2 sensor too IIRC.
