Default Camshaft sensor replacement

My car (2.5 V6) stopped last Saturday March 12th at a petrol station and would not restart. I returned the following day with an Autel diagnostic tool. There was a fault code - camshaft sensor failure. I cleared the fault and the car started ran very well until I got to 120 miles from home. I had stopped at a fuel station on the motorway. Car would not restart. Autel showed camshaft sensor wiring fault got taxi and train home.
I have ordered a new sensor from Rimmels but it is different from the one on the car. The one on the car has the lead as an integral part of the sensor itself. The new sensor has a male socket on top so requires a suitable connecting lead. I also ordered the link lead which appears to go with it. It has a socket at one end that connects with the sensor the other end has a male plug which I hope will connect with the engine harness.
My question is- will this sensor and lead marry successfully with the engine? It certainly looks more robust than the current sensor and lead that are on the car at present.
I don't want to travel 100 miles on a wild goose foray. I hope someone can tell me whether I am on the path of righteousness or evil.

As you have spotted, the early sensors had the lead integral but the later ones have a separate lead.
It plugs into the same place and is a straight forward installation.

They do look quite different, here is a shot of my old one and the new one that requires a link lead to plug it in.

Default camshaft sensor

hello Bob,
Well, I got a new sensor and lead and made the long 120 mile journey with a very obliging friend but it turned into a wild goose chase. I installed the new sensor plus lead and cleared the error on my Autel machine. Car wouldn't start and came up with sensor fail again. I noticed that the petrol pump was not starting up. I disconnected the battery and shorted the battery leads together for about 5 seconds. That seemed to clear the ECU memory but car still would not start so abandoned the project.
Do you have any ideas. I thought the cam sensor failure meant that the ignition system did not initiate but the petrol pump would work. I think I recollect that a faulty crankshaft sensor can cause the petrol pump not to start.
Do you have any theories? The frustrating thing is that the car was running beautifully until I stopped to check oil and water.

Did you check for the common fuel filter fault? If it separates pressure will be lost and the car won't start.

Thanks for your reply but how do I do that and would I need a new filter?

Strange that the same fault reappeared even with a new sensor + link lead. There was a problem with one of these link leads being incorrectly wired but I can't remember if it was the cam or crankshaft lead, only that it was Made in Egypt!

Does the rev counter needle move at all during cranking?

Good luck
