Someone please help me

Lol, probably goes without saying, but that’s the first time I’ve seen an ECU mounted to a master cylinder with a plastic zip tie.
So this made me Crack up soo hard lol, I don't have a lot of money nor time to be doing this, usually weekends I can work on it but through the week I have about 100$ a week and about 2-3hrs of work time depending on if I get 8hrs of sleep ill try the fix the harness things with all new wire and re route it along the factory wire path so its not up against the headers, and I'm still failing to se why this would cause it to die if I barely touch the throttle under load. I'm also working on videos for YouTube, when I have the time I'll post a video and send links, you guys have been so responsive and helpful . Thank yall so much
