If I an correct, most XJS's up to 1987 had single-wire, non heated oxygen sensors. I cannot seem to find the original Jaguar part number for these.

Jaguar Heritage only goes back to 1988 and shows 3-wire heated sensor #DAC6907.

Anyone know the part number for the non-heated sensors? Or a part number for a currently produced replacement?

Thanks!

The old single wires are almost generic. Only wire length and connector type make the difference.

You can buy universal types and just spice your old connector. I used AC Delco on my XJS

After some Googling I'm wondering if 'rationalization' has led manufactures to sell the 3-wire type with the idea that the heater wires could just be left unplugged if not needed for xxx-application. Although, if you had a mind to, hooking up the heaters would be easy

I think the Bosch 11051 should work Ok. It shows for a Subaru but an entry from the old JL parts interchange suggested it
