Yea that EMI noise is killing me too! I get spikes on the display that will jump to 2k-3k throwing off the IAC, making it rich. To make things even harder my MSD box is in the trunk making for a long run. I'm going to move my MSD box to the engine bay and shield the wires like you did. Thanks for making this video.
You can buy round ferrite chokes for this. Use them in pairs and you wrap the harness around the the choke at each end of the harness. Hold them in place with a cable tie or heat shrink the entire harness with the chokes inside the heat shrink. There are also ferrite beads which you can string along the length of the harness (the more the better and you heat shrink them in place too). You can run chokes and beads. Also of interest is you can buy clip on chokes (also only used in pairs and they look nicer. ** I'm unsure whether the plastic in the clip on ones are able to be reliably used in a hot engine compartment. Radio supply (ham radio) or electronic supply stores will have them. The way you have solved this problem is quite clever. I'm impressed

Absolutely, just feel free to ask any questions.

Thanks for the heads up. Nice simply fix. I am dropping in a new big block with Fitech. I,ll watch for this now.
How is that Fitech working with the blower?
Dump the aircleaner...
