Agreed that is the problem with those little fuses. Sometimes they are very hard to see even with a very small break in them.
Also by straight wired did you cut the oem harness or something? If so then maybe considering putting that back and getting the proper wiring harness for the vehicle. You can get them for as little as 5 bucks these days on
eBay or from
Sonicelectronix or
Crutchfield sometimes they are higher but might be worth doing. And "if" you did cut the oem harness then you can buy a replacement harness for those as well sometimes on
eBay with longer leads if you cut them too short on the stock one. Just something to think about.
