hello,
I am new. have a shop and our electronics guy cheated us outta some money and faq'ed off!
I am a nissan guy and drive a rb25det powered 180sx, but dont be hurt.. I love the JZ motors and what they do! I have heavy experience in electronics wiring for computers and hifi mobile audio etc.. i am getting into the wiring of engines now...

My friend just got a 2JZGTE installed in his Cefiro, I want to help him wire up his car to have power modes.. the guy who did the install left out the speedo, RPM, power mode and others.. the most important thing is the little lever that allows shifting.. must press that everytime.. haha!

I've already worked on the others and almost finshed, the speedo is difficult.. but I have a new set of printed docs to play with the ecu tommorow...

I need help with someone explain the A/T of a 2JZ, dunno much about them, but the ecu is like this, 3x30 pins.. T7a,b,c or d... not too sure.

it looks like there are more than 1 type of Over drive?
please help to tell me what to do.. I will have to make custom switch for him, all I can see is the plugs from the A/T shift lever. they are short and at the bottom of the lever mount

anyone have experience and tell me what wire goes where?

thanks guys..
Shaun.

what i have come up on this stuff..
okay there is a Over Drive button that prevent the A/T to go into gear4. this is by grounding the ecu pin OD2,

anything else?
