GM 21 circuit universal harness

Hello everyone, I'm trying to find a solution to me being cheap... lol I bought Painless's 21 ciruict gm universal harness (pretty sure their part number is just 10101). So I have a gm universal harness and I'm trying to mate it up with the factory style mopar ignition switch... if anyone has done this I'd love to hear how they did it and made the neutral safety switch work with a four speed manual trans. Thank you for your time I hope you all have a good day
