Wiring/ECU Issues

Here's a guide of mine on the diagnostic box in the engine bay: http://www.fadingworld.com/CRE/_Auto...mystified.html

Here's Toyota's Electronic Wiring Diagrams for the Supra all digitized and nicely formatted... you're in for hell...

HINT: Test for a break in E2 between the ECU and the TPS, temp sensor and AFM connector.

EDIT: Nevermind about the FC switch, that's N/A specific. On the GTE it's controlled by the ECU.
