when you say you cut the wires from the firewall, did you just solder/crimp/heatshrink them back together or what did you do?
I cut them in groups of three - for one coil at a time so I wouldn't cross them. I put numbered labels on the original coils on the fender apron, the wires and connectors to them, and the plug wires so I could keep track of everything.
I removed the plastic cover on the right side of the firewall so the splices would be covered:
I used plain old butt connectors but it would have been better to solder them.
