The plug on the car is white with position for 5 wires , only 3 are used.The plug on prc7067 is black square connector with 4 wires

black, brown,pink,brown orange. Do you know the connections?"

Anyone out there with the answer?

Try Mark Adams Steve. He used to sell them and said he knew how to retrofit the socket to the looms without the connector IIRC.

This has already caused much puzzlement. I dont think the 5 pin white connecter is or ever was a diagnostic socket, and on my loom I have this white plug (disconnected) plus the diaganostic socket near by. There are various connections on the Range Rover loom not used on the TVR but a friend of mine tells me like you has only the white socket on a 1991 loom. Diagram for the Rangie here that shows the wiring:

Strange...

MA seems to say that diagnostic connector is not the one that you say it is, but only part of the North American Spec LR looms (which TVR commonly used by coincidence).

Just so you don't all snipe at me....

There are two levels of diagnostics available with the 14CUX.

At the basic level, there is the Lucas "Fault Code Display Unit" part number PRC7067. This was fitted to all North American Spec (NAS) Land Rover (Disco, RR, Defender 1990-1995) vehicles by law, since you are not allowed to lock customers into franchised dealers only.

This gadget is about the size of an overgrown cigarette packet, and displays a two-digit number on the side to indicate any faults. Last week these became officially obsolete, but you can still get them on eBay from North America. It's a pity because I used to do a good trade in these to the far corners of the world!

Fortunately for us, most Griff and Chimaera were built with NAS engine looms. This means that they nearly all have the special socket to plug the reader into. If you don't have one, they can be easily retro-fitted.

It would be intersting to know if the wires are in the loom or at least connected to the ecu connector. The wires colours will match the ones on the fault code reader, so worth pulling the rubber boot off the ECU plug and see if you can find them. Spend is correct that some early looms dont have the socket.
