2001 defender TD5 diagnostic port

The 3 warning lamps for the brakes, abs and TC have come up on the dash. Took it to local guy who does lands, the ecu diagnostic port cable has been cut. How difficult/ easy is it to replace the port? Where can I find an idiots wiring dig for this? How do I check the abs pump is working?

Update so far...replaced the connections on the fluid reservoir and the brake warning lamp goes out now, the other two.ABS and TC remain lit.

Is that with the car stationary or moving? Don't you have to be going more than 5mph for them to go out?

Both stationary and moving, both lamps are lit from start up. I've measured the resistance of all the sensors and they are all around the 900 ohms. The front sensors are clean now, can't get the rear two out yet! The diagnostic plug on the loom has been cut off, so can't interrogate the ecu! I really need advice on where to get a new plug an a wiring diagram.

Cut the plug off a breaker and re-join to yours by wire colour

It's finding a breaker where they are willing to cut the socket off. LR don't sell them separately. Arrrgghh

Are these any good to you Smudger?

That's the plug, he needs the socket. They are available on Ebay often at extortionate prices for a one off.

Or cut one of these up

Yep, but the females are not the panel mount variety and they are expensive. Bit of searching and the correct item can be found for as little as £2.50.

I'll keep my nose out!
