80 interior lighting

[David Miller]

My '90 80Q doesn't havev ery good interior lighting.  In fact, it sucks.
There's only the small light by the manual sunroof lever to light the entire
car when dark.  On my most recent trip to the junkyard (yesterday), I picked
up the interior lights above the doors off of both a 5000S and a 5000tq.
The pieces differ as the 5000tq lights can be set to light up when a door is
open while the 5000S lights can only be set on/off (if anyone's interested,
I'll take pictures of both units).  The units look pretty much identical to
the blank space I have above my doors, where I figure lights would go if I
had a 90.  I wsa hoping that there'd be a wiring harness for the lights
behind the panels in my car, but regretfully, there weren't.  I currently
have the 5000S light panels installed with the circuitry hooked up to a
small battery that I attached to the panel.  While I do like having the
on/off ability of the lights, I'd love it if the lights could come on when
the doors open.  Any suggestions?

Thanks,
