No interior power ammater wire not getting power only when the key is in acc

So I have a 1968 dart gt i ended up having to try and get the horn working to pass inspection to transfer title. So I pop the cover off find previous own had not connected it text to ask why said old wheel had a issue with it sticking so he just decided not to. So I hook it up it honks once and I lost all power to the interior. No power to the fuse box checked the fusable link power on bothe sides end up tearing the cluster out to check ammeter it's got power to one lug bypass it by moving the one with power to the opposite side. After I had powrr to the fuse box but still could not get headlights on or interior. Although not sure if the dome light worked before hand will need to check with test light when I get off work.

Anyways on to now so when the key is turned to acc it no longer gets power to the ammeter wire no crank no anything i am brand new to mopar and am at a loss if anyone can help
