=Wiring=

==Wiring S1/S2==

'''This applies to the series 1 and 2 automatic transmissions ONLY.'''

On the drivers side of the jatco automatic, there is a 8 pin plug on the shift selector.  Tracing it back towards the battery you will find its other end.

A few of these wires will enable you to start your car.

The following is the wiring:
Red + Black and white stripe - Reverse; on the manual gearbox there is a 2 wire plug at the drivers side on the base of the bellhousing.  These must be connected, they are universal, as it is a switch, hooking them up allows you to have reverse lights.

Red with black stripe + Black with Blue stripe- Neutral; join these two into the neutral switch on the gearbox.

Red with black stripe + Black with yellow stripe- Park; join these two together to disable the inhibitor switch, this one will allow you to start your car.

Congrats, you now may start your car.  To test with gearbox out, make sure the starter motor is grounded to the engine block.


==Wiring S3==

S3 wiring is different.  The speed sender connection is a seperate loom from memory - just use the auto loom for that - easy.

There is a grey 2 pin connector with really thick wires near the battery - bridge these 2 wires to disable the start inhibit - easy.

For the rest, I used the connectors from both looms to make a custom loom, that is really the only way to go with an S3.

In the same area as the grey 2 pin connector there is a grey 8 pin, you want to use this plug from your auto box to make the custom loom.

Looking at the front of the connector from the auto loom, it goes like this:

On mine the colours were:

*1 – Black
*2 – Orange
*3 – Red
*4 – Yellow
*5 – Blue
*6 – Brown
*7 – White
*8 – N/C

Connect Pin 1 and Pin 5 to the neutral switch, and Pin 1 and Pin 6 to the reverse switch, and you're done.

Now, my car is actually one of the very last s3s to be built, and actually had a 300ZX auto box, but I am now 99% certain that the early s3s use identical wiring

You don't really need to connect the neutral switch, all it does is improve fuel economy when the car is in neutral (i.e. never).  But since I was making a new loom anyway, I figured I might as well do it.

==Wiring HR31==

Hey, just like to clear up the pinout on the inhibitor switch plug on HR31's to make them start and reversing lights work - I just worked this one out today. This is the grey 8 pin plug near the battery on an auto HR31:

Splice 1 to 7 to bypass the inhibitor switch, which you can now snip off! Connect 1 and 6 to the reverse switch on your newly installed manual gearbox and voila! My car had the inhibitor switch jammed under the brake booster all taped up, the other unused wires (2, 3, 4, 5, & 8.) aren't needed and can be chopped. Colours are all different to S3 Ausdel as well.
