What Is This? & where can i find a '70 chev 350 small block wiring diagram?

[darkone]

there are a few of these under my hood. what are they, and what can they be replaced with? theres a small glass something inside (probably fuse) thats broken. but if i replace them what should i replace them with?

also, i need a wiring diagram for everything from interior under the dash, to under the hood etc. any help would be greatly appreciated. thanks in advance for the help!

Those are fuse holders for 4A fuses. They are for the ammeter. Heres a diagram with fuse holders shown with arrows.

Those are in line fuses - one is for the ammeter, not sure on the other.

I think they take a SFE4 fuse. You should be able to replace them with any in line fuse of similar amperage. They are similar to a fusible link, but replaceable.

Here is a link for the elec. diagram:
