Right...I think I have seen your driver before now.
My driver has the delay built in and is activated by the button on the driver....not in the wire.
So....I push the button, start cranking and 7 seconds later the glow comes on automatically and lasts for one minuite.
If the engine quits before the driver turns off, I just push the button again and the 7 second delay starts over.
