I highly recommend the purple wire modification. It does wonders for
cold weather starting. It causes the GP to stay on to the end of the
timer no matter what.

I thought when the glow light goes out the plugs are done. I now
assume I am wrong?
My understanding is that the glow plug relay adjusts the dash lamp
illumination time based on ambient temperature (or maybe coolant
temperature?). The colder it is, the longer the lamp stays on and the
more time the plugs have to heat the prechambers. The idea is that when
the lamp goes out, the plugs are hot and the car should be ready to
start. The plugs aren't actually de-energized at that point, they stay
on until the starter is released or the cycle timer expires.
