you need a defrost relay (well, if you want it to work, that is)
it's in the 5th position from left.
1986 Spider Graduate Lights
It is a standard relay, like the horn relay (originally a metal Sipea 0440 relay, so any equivalent relay)
when tightening the J hooks, don't just tighten them as far as they go...you need to leave a small gap.
Did you fit the rear hooks as well (the ones that screw in place of those little chrome turret R2D2 things?)
The hardtop light can itself be adjusted to come on as the interior lights come on.
plus that little eyeball light (I suppose a reading light designed for any rear passengers/hitchhikers we pick up, or maybe just to keep the dog happy
The light is great when it works but a horribly cheap design and the plastic switch breaks, then it becomes useless.
Someone on here has done new seals for the hard top.
