Running a M103 out of the car....

I am building the complete drivetrain of a 2001 300e into a streetrod. :surrender: Don't shoot me...lol
To start off, I bought a rusted but running car, so have all the relevant bits to make it run.

Then we built it into the body, but from the start knew that the injection would not fit in the engine bay, so we will have to make an intake manifold and run it off Weber sidies. That is not the problem......yet.;)

What I do need help with is figuring out what is the minimum bits required to make the old girl fire.........i.e the least amount of electronics to be bolted back on / connected to get spark....nothing on the injection side needs to work.. and using as much of what I have???

I'm confused. You say that you want to run an M103 out of the car. You say that you are building the complete drivetrain of a 2001 300E into a streetrod.
But a 2001 300E is not a 124 chassis vehicle, the subject of this forum.
And a 2001 300E certainly does not have an M103.

Last summer I bought a wrecked 1990 300TE (which has the same drivetrain as your donor car) and the seller was nice enough to sell off a bunch of underhood components after cutting the wiring harness all the hell. Thanks. Well I removed the whole engine harness from the car (or what was left of it) so I can tell you that you should do the same.
Just about everything you will need to keep the Jetronic injection sytem operational is part and parcel of that wiring harness that lays on the engine. There's a branch that goes through the firewall by the RH hood hinge and that goes to the oxygen sensor. AFAIK the only stuff *not* on that harness would be the fuel pump wiring (and, of course, the fuel pumps themselves).
