Major interior lighting issue

My 96 tacoma that I just bought has no interior lights. Even the blinker lights won't come on or work. I just bought the truck. Planning a complete restoration but I need to get this fixed first. There is a big aftermarket radio the prior owner put in and it looks like a nightmare. I am mechanically inclined but when it comes to wiring I am clueless. I have checked all the fuses under the dash and hood. They are all good. Any help would be greatly appreciated.

 

What do you mean by “no interior lights”? No dome light, no instrument panel lights or something else? Does blinker lights mean the turns signals or the indicators in the dash or both?
