Does anyone know where the 3A connector is in the attached wiring diagram (pg 5, pg 8)? I've searched everywhere including ALLDATA and no luck. Thanks in advance for anyone who has found this!
Look in the Relay Locations pages of the Electrical Wiring Diagram (more info) published by Toyota, EM1291U. Connector 3A is part of J/B (Junction Block) No. 3, towards the center of the instrument panel.
