2. You need the Excel spreadsheet, some tools, some knowledge, one PCM (programmed correctly and without VATS), and two connectors for the PCM.
3. 4 Wires (about 10 feet in length or less, maybe 15 but I doubt it). And 4 ways of splicing those wires into some stock trans wires. Also, 4 crimp pins for installing on the PCM side. Get the pins and wire from S10Wildside and his website called www.eficonnection.com or EFI Connection.
If you really want to be a wild man in the future after you get the 12200411 swap done, swap to LS1 coils on your old skool 350 chebby. S10Wildside sells the conversion parts to run a true LS1 setup on a true 350 inch motor (not a measly 346, I want my 4cu in., oh and torque)
If you live in Los Angeles, I'll do the swap with you and teach you how to do it. 2-3 hours. I might have spare wire from when I did mine.
