There is a very large class of people that own 65/66 Mustangs that, as far as I can tell, anyway, have been, for the most part, ignored entirely. They don't really want that 100 pt. show car that is so nice and was soooo expensive that they're afraid to drive it, they also don't want to make their car capable of achieving warp factor three. They just want this car that they dearly love to be able to cruise around smoothly and reliably, without having it dump them out on the side of the road or have it start making weird noises or belching out big clouds of funky-smelling smoke. And I think, truth be told, that this is by far the largest class of Mustang owners. They take their car to some technician when what they actually need is a mechanic, and this, frequently, does not work out very well at all for the owner. They don't want to re-engineer the entire car, they just want someone to fix what broke. These are the people that I am trying help out with this blog. Some problems require a little bit of back and forth, as in, "Try this." "I tried that and it didn't change anything."
" Oh. well, you probably need to try that." " I tried that and it helped, but it still isn't quite right." "Now you need to try this...." If you go to http://www.allfordmustangs.com/ and then go to the classics forums, you will be able to do that with a pretty hefty gathering of some very knowledgeable people that also happen to be very friendly. None of that ridiculous one-upmanship, no flaming or abuse, none of that stuff. Just good, solid advice from people that know what they are talking about.

1965 1966 Mustang Seat Belt Warning Light

Here's what the light looks like on the dash, along with a quick sketch of how it's wired. There is a green wire that plugs into the accessory feed, which is behind the instrument cluster. It will be a three prong, female plug. That green wire splits into two green wires, one of which goes to the light on the dash, and the other goes to the switch relay. There will also be a violet colored wire coming out of the light, and it also goes to the switch relay. The relay grounds itself out on the body of the car.

What might cause the seat belt light to stay on while driving? Sometimes dim others bright. Thanks d

I am sooo sorry that this took so long. I just plain forgot about this. Assuming that everything is wired correctly, it would just about have to be the relay that works as a path to ground. If that thing does what it's supposed to do, the light doesn't have a ground, so it can't light up.Again, I apologize for taking so long.
