Hi,
Trying to find the correct Engine Temperature Sensor (for ECU signal not gauge) for my '75 Double Six Coupe. All the ones I am able to find have the standard Bosch Injector type connector. My car has a sensor which is also 2 wire but smaller top diameter and with a smaller female plug sensor has square corners on the top but rounded corners on the bottom.
Wondered if anyone has a part number or advice to help me get one of these.
Thanks all

Hi,
The ECU temperature sensor is a critical part of the fuel injection kit so you have to buy the correct Bosch item. No other will do. However, be warned that Bosch did have a batch of sensors which, for some strange reason, were not produced to spec. How do I know? I bought several before I found one which complied with the specs listed in the XJ workshop manual. I even wrote to Bosch to confirm the spec hadn't changed and I had a reply confirming the original specification. Hence, I'd recommend that you buy one from a Bosch automotive dealer and test its resistance reading before you leave the dealer. I believe the Bosch part number may be 0280130014. The dealer should be able to confirm that number fits the V12 before ordering it. Mike.
