I'm currently under way putting the mk2 1242 8v Punto into my Panda.
Ive purchased an ECU kit similar to the picture below.


Can any body help me identify the immobiliser circuit pin outs?
I.e. where the immobiliser ring connects?
From certain threads there are discussion of "code boxes", is this something I am missing or is it possible to complete the immobiliser circuit with the components in the attached image?

With almost no knowledge at all about your situation I think the two pin transponder aerial ring that goes on the ignition barrel connects to the two wires of the CAN data bus, The CAN data bus travels all around the car so that the various devices can communicate with each other. If you had a punto I suppose there would be a plug coming off the can bus you would connect to.

I'd be getting a full wiring loom out a scrap punto
mashing it up - to allow you to connect to the panda's or get a donor panda loom to make it up

Bearing it mind you'll be going from the Carb / SPI

To a MPI, with about everything else

Since you wont have airbags and P/S / ABS you may find that a problem as well, might need a punto binicle as well?

As for the Rings, its not known without a haynes or autodata wiring diagram

There are two looms you need the engine management loom and the main loom that runs from the engine bay all around the car. You also need the engine compartment fusebox and the cabin fusebox. You can just remove all wires and plugs you won't be using.

If your look at the pic you will see the ignition ring plugs into a small 2 pin connector that comes from one of the plugs connected to the cabin fusebox under the steering wheel.

I'm in the process of doing a similar conversion.

That's great! Thanks for the detailed response!

I have the compartment fuse box to which the purple connector of the engine bay loom connects to. I assume the 2 pin connector of the ignition ring goes straight to the compartment fusebox and then straight to the ecu, via the engine loom.

It would be of great help if you could identify and picture which pins the 2 pin connector from the ignition ring joins onto the compartment fusebox?! ? (since I don't have that 'main' loom)

Also, is there a particular reason for which I require the engine bay fusebox? I was hoping to power the punto compartment fusebox with an inline fuse directly from the battery. And continue to run the remaining ancillaries off the panda fusebox.

Thanks again!

The 2 pin ignition ring seems to run away from the fusebox along the loom (marked in red). I'm not sure where it goes, I'm assuming to the engine fusebox which is then connected to the ECU via the engine loom.

I hope these pictures help you identify what goes where.


The engine loom connects to the fusebox in the engine bay. See 2nd picture (marked pic 1) cable 1 is the engine loom that connects underneath the engine fusebox. Cable 2 is the loom that connects the engine fusebox to the cabin fusebox.



Here are the two fuseboxes off the car connected via the brown plug with purple clip. The box on the right is the engine fusebox and on the left the cabin fusebox.
