Stevo- if I was the only one driving the turtle I would do a 'field repair' like you describe , but since the wife's car is hibernating for the winter a 'blonde-proof' solution works best

.
The relay is in now and works perfectly , my lite comes on and as soon as it's off the turtle starts like a gas engine ,

.Bring on the winter !
