I have currently been entrusted to get my father in laws 1992 jaguar xjs v12 running again he sent it to get the headliner and a few other cosmetic details buttoned up at a shop turns out they put it behind the shop and never fixed the problem....... Now there is an even bigger problem when he went to get the car from the shop 3 years later after getting the run around there was a giant rats nest in it thankfully they didn't eat to much wiring all that i can tell is a few injector wires and a wiring harness on what looks to be the coil does anyone know where to get this 4 wire harness at or what its even called specifically so I can look f or it better

 

Um, you might get more answers over in the XJS section:

Welcome.

As Elinor said, please repost in the XJ-S area.

Your 92 is also know as a "Marelli car", which means little to anyone EXCEPT the XJ-S group.

It has different stuff to the earlier "Lucas" cars.
