Key on and cranking wire

Have a wiring issue somewhere or I have something hooked up wrong. Installed a 99 4.8 in my 72 c10 that had a 350. Used the pink wire coming off the bulkhead as shown in the photo to give me key on and cranking power and to power the fuel pump relay. Engine starts and runs fine, until after about 30 seconds the pink wire starts to get hot and will burn up if I don't shut it down. What did I do wrong?
