Neutral Start Switch Pin Out

[JetspeedCamry]

This may be more directed ti 88LE, or Ratko, but does anyone have a pinout diagram for the plug that goes onto the auto transmission on a Gen 2?
There are looms, 1 is for the reverse lights (2 wires), one is for the O/D (2 or 1 wire/s) and the other is a big plug that goes onto the Neutral Start Switch. I need the pin out for the Neutral Start Switch.

Thanks

My EWD manual only shows the pin out for 2 wires on the neutral start switch.


Neutral start s/w:

1 - 2, 2 - 3: Closed with A/T shift lever in P or N position.


Pin 2 = black wire with white stripe

Pin 3 = black wire


This is for a 3S-FE w/A140E. So I don't know if its the same for a 2VZ-FE with A540.

One thing you can do is move the lever attached to the neutral start s/w. You want the lever all the way to the left. Then probe pins 2 and 3 with a DMM and check for continuity. 2 of the pins will have continuity with each other.



P.S. Let me know if you want the pages out of the manual. I'll scan them for you.

Thanks 88, thats fine then. There are 2 wires on the plug, black and black w/ wihte, so thats fine. Just theres alot of other wires on the same plug, and no idea what they are!

My manual shows a 9 pin plug for the neutral start s/w. And I found somemore info in the manual under ECT and A/T indicator.

The other pins connect to the A/T indicator (gear indicator on the dash).


The way that it works is that pin 6 is common. It gets switched to the other pins (1, 4, 5, 7, 8, and 9).

Pin 6 to pin 1 = Park

Pin 6 to pin 5 = Reverse

Pin 6 to pin 7 = Neutral

Pin 6 to pin 8 = Drive

Pin 6 to pin 9 = 2nd

Pin 6 to pin 4 = Low



Pin 6 = Red wire with blue stripe

Pin 1 = Green wire with white stripe

Pin 5 = Red wire with black stripe

Pin 7 = Red wire

Pin 8 = Black wire with orange stripe

Pin 9 = Orange wire

Pin 4 = Yellow wire with blue stripe



P.S. The pin numbers are for the plug on the wiring harness.

Thanks 88, that means there not important :P!

No prob. And yup the other wires are not important.

The only wires you need to mess with are the black and black/white wire. IE: connect them together.


From Ratko's tranny swap page:

Park/Neutral Switch - This is the most important wiring you need to do because the car wont start without it. Basically the car will only start if the shifter is in "P" Park or "N" Neutral, and without the auto tranny and shifter there, we need to fool the ECU and make it permanently in Park/Neutral =) Find the large harness that went to the gear selector switch on the front of the old auto tranny. Remove the loom that hides all the wires and find the Black wire and the Black w/ White Stripe wire. These need to have continuity with each other so wire them up.
