Two questions that are sort of related:

Is there a wiring diagram that is applicable to the 1975 JH available? Don't need a free one. I got one from Jensen Owner's Club and it is good but seems to be for earlier cars and probably Euro spec.

Second: Did the 75 come with an anti run on valve? I have 2 wires going to a sender that is T'ed into the oil pressure port and am trying to figure out what they are supposed to do.

Thanks

Late JH’s wiring benefits from having both a GT and JH diagram.
Yes later cars had the anti run on valve.

Thanks for that. I looked around underhood, any idea where the ARV would be hidden?

Pretty sure it’s by the stromberg carb closest to the firewall, it’s been so long since I removed all that stuff, but that had vac line’s in and out.
The wires by the oil pickup ring a bell but I’d have to look at a wiring diagram and I won’t be near one for a couple months, sorry.
