Steering Column Problem

[ch3vy4life]

Hello, ok so i recently picked up a 1985 k-5 blazer, The guy i bought it from was having a ground issue something would pop the fuse on the firewall when he started it. So he took alot of stuff apart to try and find the problem. Finally he unpluged the A/c and everything is fine now, no issues. But now im left to put everything back together im having a problem putting the steering column wiring back in. To start it im having to put like a nail in that blue box and slide it to the left. im not sure what to do so im hoping one of you do. Heres a couple pics i took of it.
