whats this ground for ?
 

why is the insulation under the hood grounded to firewall? ...i put on a fiberglass hood without the insulation ...can i just eliminate that ground or should i do something with it?

Yes you can. I think it was originally for the underhood light. Its not for the insulation itself. Its not going to work now with the fiberglass.

the light wont work ? ...the big big braided ground wire was for that lil ass light?
is there another way to make the light work?

Right, there was an under hood light that is stock equipment.

The braided ground wire is probably going from your engine block to firewall, or at least it should be. The under hood light is useless. Even if you had to work on the car in the dark, this light will not make it much easier.

If you REALLY wanted the light that badly run a ground wire right to it...

heres the ground im referring to ....

another interesting thing i found on the bottom side of the stock hood ...is this done at the factory?..looks like it was cut out for scoops but the is no evidence of being repaired from the top

Looks like someone was gonna do something to it before you got ahold of the car. Do this, take the light off the hood but leave the wiring connected and hold it in your hand and move it to see if it comes on.

not really worried about the light but i will try to ground it if it dossnt work (havent even put a bulb in it yet

....just seems to me that big ground wire has some other purpose than grounding that light ...but cant imagine what

If that's the ground that goes to the hood that's all it's for. There's no other electrical device attached to a hood.
