Thanks for the input guys. I've tried Jaycar and no luck there. Also spoke to Nizpro today and Steve reckons he's never been able to get hold of them.
I've got a contact at Hella and will be sending him a pic of what I need tomorrow.
Fingers crossed, but I don't like my chances.

As for aftermarket plugs..I went to the largest electrical automotive wholesaler in Melbourne and the only Crank Angle Sensor type plug they had didn't fit. Unless the Hella contact can assist I'll either have to solder the new loom to the old wires or put in some new connectors to join old to new.
All a bit messy I reckon.

Have you asked Jaycar? Their usually OK for this sort of thing...

a good electronics supplier might be able to help. another option is to replace all the nissan plugs with aftermarket weatherpak connectors.

then it'll be better than OEM.

I've just run into another stumbling block trying to wire up a Microtech loom with all the Nissan CA18DET plugs. After finally unclipping the terminals from within the original Nissan crank angle sensor I headed on down to a auto electrical wholesaler. He advised me that he had no terminal that would match the original Nissan ones. I then went to an auto electrician who referred me back to the wholesaler I'd already been to!!
I then tried the Nissan Dealer who said Nissan did not sell parts for wiring looms only the whole loom. I know I can solder the original wires onto my new loom but I was hoping to avoid this.
Does anyone know where to get hold of these terminals??
