Not only the horn wires but all 3 or 4 red wires that are hot. I think two have a in line fuse and give power to the whole car

Hi O,
Might this link help?
https://www.corvetteforum.com/forums...ay-1973-a.html
Regards,
Alan

This is the best I can find on google…but not a 73.
It matches my 71. Might be a hint or two in the picture for you.

This is the connections on my 73. The 3 hot red wires on the post and
the two plug-ins in the bottom.

Thanks guys. One of the red wires goes to the starter and powers the entire car. It has a fusible link and mine burnt. For now I just twisted it together for power but I need to fix it right. How do I add and fusible link or another simpler fuse?
