Thanks guys.

<edit>
I also found this stuff at Merlin Motorsport. I reckon I'm going to have to get something like 20-30mm sleeving to get over the connector block!

The red fire sleeving looks like what I have on the old sensor. More pricey especially as I'd have to get a large bore to fit over the connector.
Simon Taylor posted a photo of his a while back that had the silver thermal sleeving, so I'm thinking that that will be sufficient - and the reflective qualities may even be better.

Are the Car Builders' folks quick at delivering?

Car builers are tops at deliver.

With the connector block at one end and the sensor at the other there's no way (without cutting the wires) to get the old one onto the new one.

I have not seen this particular connector as to whether it is possible to remove the pins from the connectors body or not, but reading the thread, it sounds as if you have to reverse the wires anyway ..... how do you go about this without cutting them if the connector is non reversible which I suspect it is ?
I am not offering any suggestions, just interested

That is the big question!
Time constraints and work have meant that I haven't had a chance to change it yet. The new sensor only arrived this morning and I've just ordered some heat sleeving to go onto it. I did manage to 'scope out the job' of changing it but work commitments will most likely mean that I'll have to get someone to do it for me. No idea how Clee got to it via the driver's side wheel arch - looks well fiddly. Also the workshop manual reckons that it's accessed from underneath - in a rather blase manner, it must be said.

Of course, when the car is cold, it all works just fine. The old sensor tests out at 200 ohms and the engine runs great. I'm pretty sure that if I take it anywhere it'll go again - adding a couple of hours to any journey! Once the sleeving arrives, I'll get it all fitted and let you know. That'll be an 'interesting' first trip after the new one is fitted.
If I'd known, I'd have got the RAC guy to test the resistance on the connector when it was dead - then we'd know for sure.

The connectors are wired correctly but match red to white and vice versa .The problem only surfaces when either those connectors are fecked/chopped or you get a non #60 sensor .Logic would dictate that you connect red to red ....
This may be the reason that there is a 60 number for the Alp version .

I dunno ...all I know is what it is ....

It is a pain and does depend on arm length and hand size .I have a woman's hand

Thanks Lee, I now know what you are all talking about .... what I would like to see however, is a pic of the actual connector, if anyone can spare a moment to post one up for me please.

Here you go John. Some shots of the whole sensor (notably without any shielding) and the connector.

Note that there's a twist in the wires that's obscured in the front-on shot of the connector. Hope this gives you what you need.

Thanks Jon, it is as I thought, the pins can be removed, so if you wanted to slip some heat shielding tubing over the cables of the correct size, clearly removing the pins would achieve this. I you want info of how to get the pins out, let me know

Thanks John.

I've order some sleeving that should fit over the connector, so hopefully that won't be required. But you never, know - I might be in touch!

Quick update:

Changed the thermostat yesterday and after running it with the 'stat open for about 12 minutes (better water temp behaviour, BTW), engine. TDC Sensor reading open circuit instead of 200 ohms.
That'll be the problem, then.

Just waiting for my heat shielding to arrive then hopefully back on the road!

Hi John, If you have any information on how to take the pins out that would be great.

I am also changing my sensor and if I can swap the shield then I can throw it together tonight.

Hi Jon, no problem. First prise back the clips either side of the casing, and the rear cover should fold away from the main body revealing the wire entry points. There should be a rubber grommet around each wire which can be pulled out.
Next...see pics below... The actual pin has two barbs, and carefully, without damaging the actual pin, with a jewellers screwdriver or similar, press each barb into the pins body, then you can pull the pin out through the back of the connector. It is difficult to actually see the barbs down the tube, so to speak, but you can feel for them. If you look at the second pic, you can see where the barbs are in relation to the open sides of the pin, ie:- the barbs are at 90` from the open sides. You can easily see the open sides of the pin. It is a bit fiddly to do, but you don`t have to use much force. Clearly, all you have to do when replacing the pins into the connector, is reset the barbs as the pics below show.
I have used this method for years without too much trouble, but just recently, I have made a tool ( a tube really ) to slide over the pin, out of 4 thou` shim stock, which works a treat and saves all the fiddling.
Before you start, make sure you have a pic, or make a note of which colour wire goes to which side of the connector, the last thing you want is the wires reversed.
Once you get the hang of the first pin, you will find the other is easy.
