I have a 1985 XJS and someone had cut off many of the wires in the engine compartment. There is a single heavy-gauge white wire with blue tracer which has a connector and it is just floating around inside. There are a few other wires which have been cut off. Also, which wires go to the oil pressure sensor and light? I'm sorry i bought this car, but would like to resurrect it. It has low miles and a good engine. The interior is a mess, no gauges work, windows don't work, but I don't care about that now, as long as it is driveable. I should have gotten the old Corvette.
You need the S57 wiring guide. It will be very helpful. PM your email address and I can send it to you.
An older Corvette would be a lot easier as far as electrics go, yes. A similar vintage....1985.....not so much
Search the archives on bring the gauges back to life. Tons of info; not that hard. Usually just a matter of removing the cluster, cleaning all the contacts, and adding an extra ground for good measure.

As for the wires, brother, ya got to be a little more specific. Under the engine bay in an XJS is about the size of Rhode Island, and what I would need to help is if you could at LEAST give the zip code or the area of the engine bay you're finding wires.
I would LOVE to see the twin turbo set up.
The oil sending units and wiring are RIGHT behind the throttle cap stan (wheel with the 2 arms) - in the v12 XJS that is.
