    High idle switch 6.5 diesel

    I have a 6.5 diesel, I’ve seen people make high idle switches for them, but I guess they buy pins from gm(or used to) to plug the wire into the pcm. My question is, can I just make my own pin? Can I just basically push the wire in? Does anyone have a couple gm pins I can buy? I appreciate it
