I recently acquired 1994 XJS V12, fixed the major issues I've ran into, now I'm stuck with my check engine light on fault code FF34 and my reverse lights don't come on, and lastly my radio does not work. I guess what I'm getting at is a few things.
1. Can I replace my cassette deck with an aftermarket one as long as it's a single din? I did that in my 1994 XJ6 with no problem can be so simple and a little FYI an Isuzu wiring harness will work in an xj6.
2. I've checked all the fuses and bulbs and they are all fine, okay I don't know if I checked the reverse light fuse because I don't know where to find it.
3. What can I do to remove the FF34 fault?
Any help will be appreciated

This should get you the electrical information you are looking for. http://www.captainjaguarscathouse.co..._Reference.htm In your case I would be looking for a bad ground for the lights. I had a 93 xj-s and it was a great car. I had installed an Alpine CD changer in the 93 and it worked well I would ask why not an I-Pod. Hope this helps!
FF34 on your XJS V12 is a circuit fault for the "A" Bank Injectors. I'd be hunting for a chafed wire in the engine harness, or broken or loose fitting injector connectors on the RH Bank. The ECM has to detect a shorted or open circuit to set that fault.
Happy Hunting!
