1976 jaguar xj12 remote start?

i have a customer coming tomorrow wanting a remote start/keyless entry in his 76 jag. i was doubtful thinking its carburated but he says its fuel injected so if so im assuming its possible? anyone have any info on this car? i know its a shot in the dark but work has been slow so ill take all the work i can get!

I had a 78 Jag and its fuel injected.  If it is, then its simple.  Everthing is run off relays under the hood.  Go to ingition switch, there will be be 12 volt, stater (WHITE/ yellow), and ingition (WHITE/ pink), white(acc) and maybe PURPLE / black, check with meter,  simple install.  Door locks in centre console at master switch.  Tach comes into the dash (WHITE/ black).  Please double check, Jag wiring is a guess at best, but it makes sense, when it works.
