New Member Struggling here...

I have a Jaguar XJ 2014 [VIN V621xxx] with a cracked RH taillight and there is moisture in there
and the taillight does not work.
I was thinking of removing the LH taillight and trying it on the RH connector to see if the RH line and fuse
are still OK.
Then I was going to try the 'broken' RH taillight on the known working LH side... but I don't want to blow
the fuse on the good LH side with a possibly bad RH taillight.
I don't know if the fuse box in the rear seat divider is the correct fuse box either?
It has no lid with a chart that says what relay goes to what fuse.
Does anyone have a proper fuse box location and identification chart of what relay
number works for what part and where that fuse is located in the fusebox layout for a 2014 Jaguar XJ?
This LED taillight is $$$$ on the web so if anyone knows of a trusted reseller for Jaguar parts
in California LAX 90045 area I would love the info as well.
Open to advice!
Thanks!
