69 C10 starting issue

[deathlinx]

i have a 1969 C10 396. i just changed out the starter solenoid because the starters from advanced and auto zone cross referance over did not fit. so i just got a new solenoid and had them test it on old starter. everything tested just fine and passed. i installed starter back on truck connected my positive wire and my activation wire from ignition switch. now when i try to start my truck nothing happens. when i turn the key to the start position the brake light on the dash lights up. the truck started prior to changing out the parts. i dont know if there is something missing, a blown fuse...anything. i need help from anyone that may be able to help
