It was simple really I had bought a monotech dpfi to mpfi harness I had a done certainly right next to my hatch my 91 sedan dx and just swapped it all over ledal assembly was kinda simple just time consuming it took me about a week just to double check everything if you wanna know what you need to do the complete swapping I'll be glad to help
