Here's the blog post detailing all the hassles. It really wasn't that bad; I only screamed and wanted to punch a wall one time. The whole operation— from measuring wires and crimping ends to the end of the test drive—was about six hours, including the dreaded driver chase. The only tricky part so far was getting the adaptor cables to talk to the computer. Once that happened it all seemed to work smoothly.
I did drive the car a few miles on the stock spark tables. It already seems better.
Next thing is I'll reset the rev limiter to like 3500 RPM just to test it.
Then its on to making a custom ignition curve for this particular motor. Hopefully that will be fun.
