My 1996 xj12 has an electrochromic rear view mirror which I find
extremely useful. At night it works like a charm, so well that I wanted
to get a electrochromic drivers side view mirror also, but unfortunately
no 1995/1996 came with such a mirror. This was first introduced in 1997
on the x308 which could be had with electrochromic side view mirrors,
driver’s and passenger’s.
I decided this is simple enough: I’ll just get a 1998 driver’s
electrochromic side view mirror and run a wire to my rear view mirror
and hook it up there so that when my rear view mirror is dimming the
side view mirror will also dim. On top of that 1996 side view mirror is
easily replaced by a 1998 one - it fits perfectly.
I handed the job to my skilled mechanic, who is very good. He is mostly
working on european cars.
After a while he called back saying that the wire/device that activates
the dimming is built into the rear view mirror and therefore cannot be
accessed without taking the mirror apart which does not sound appealing.
In addition this wire or device is activated by a current much lower
than the 12v delivered by the main battery. If I were to just hook up
the 1998 electrochromic connector on the side view mirror to power it
would just burn out.
He also told me that the side view mirrors on the 1998 are slaves of the
rear view mirror on the 1998 so that without having a 1998 rear view
mirror I would not be able to make my side view mirror work on my 1996
xj12. Caught !!! Nothing is ever simple.
Has anyone any comments to add to this? A different
experience/suggestions ? Does anyone have a 1998 electrical guide which
should show the layout for the electrochromatic rear view mirror ?
It took me 2 years to get this far - I am not giving up yet.
