ZF Auto inhibit switch HELP

Recommended Posts

Well as the title says I have a 300 tdi auto the last of the 300's before the ecu's . I have fitted the engine and box from what I was lead to believe was a late classic tdi auto. every thing is spot on apart from wiring the auto inhibit. For competition reasons the vehicle must only start in Park and neutral. :huh:

There are 6 wires coming from the auto and tranfer box and so far I have managed to work the following out and all working so far:

Dark Green = live feed into the switch

Light green with brown trace reverse feed out

Black purple feed to the tranfer box, difflock light, black return out.

Black with light brown trace coming out which has a orange with black trace joined on at the end,

Seperate yellow wire too.

Any help would be really appreciated with this !! :o

cheers nathan

I can't remember the colur codes but when I done an auto install I simply identified the wires using a multi meter. There should be a pair that are closed when in neutral or park and open in all other gears. Wire these between ignition switch and starter relay.

Hi Mark,

The two wires i have left were the yellow and the Black with the brown trace which is coupled to the orange and black a little further down on the bit of a loom.

It was this wire that is earthed in park and neutral, the yellow ? till tomorrow i suppose

thanks

Nathan, can I recommend you wire the inhibitor so it only starts if you are in park OR if you have your foot on the brake - it just makes it faster to restart during a competition and will still pass scruteneering B)
