88 Jaguar xj6 - mounting kit

very few, if any jags have wire harnesses (i cant find them), so a hardwire or running new wire might be necessery but if you look hard enough maybe you can find some info.  as far as the dash kit goes, i have never been able to find one, and i have looked for the same car but a '90 (they are the same) and i just ended up using ABS and some creativity to make my own.  you can also use a din trim ring that you can buy at a place like best buy for $10-11 and secure it to the dash bezel and pop your sleeve and deck in.  i always write down the wire code or whatever i had to do to get the job done and make everything work properly and i'll try to find it for you.

good luck
