well right now I have decoded most of the d-jet input out put stuff but it is way off from what I need. I am still trying to work out the general relays and figure it out. I found some old stuff a couple of minutes ago from tomguy but looks like this is the first 280se 4.5 that is actually being done. Any clue where the fuel pump meets up with the system, there is a large red wire with a cloth braided cover, looks like it is very important, could that be it?

I have to start figuring out how to go from a positive engine computer to a grounded engine computer.
what is the deal with switching out the ignition system? I understand the injection system but I am still trying to get a grasp of the whole spark scene. what do I use for engine speed inputs? Do I have to add a tach wire if I pull the distributor a replace it with a mega squirt ignition system?
