Guys,
Just got one last wire to connect before sending the first 1UZFE powered Lexus Cobra in the UK to the trimmers.
I need to finalise which wire I send 12v down into the ECU to switch overdrive on and off.
I have a four connector ECU and loom with 28/16/22/34 pin from a 1993 LS400 and looking at the wiring diagrams from this site and others, although none give a definitive answer I can see, I tend to think that pin 6 ( blue and yellow wire) in the 28 pin plug is the one to connect to the overdrive switch to send 12v down when I want o/d.
Obviously I dont want to risk frying the ECU so can anyone confirm my thoughts or give me a definitive answer re the correct pin for the overdrive signal?
cheers,
Tony
