Where to start? Trying to learn EFI. Hi, I am fairly new and am about to do a LSx conversion into a 70 Chevelle. I have read the build threads located in Conversions, but I am totaly clueless on how to get started. First of my engine came from a wrecked 1998 Camaro SS. I have the engine, which is mostly complete except for some fastners, I have the ECM which carries a service number of 16238212. I have a wire harness, the blue plug connector will plug into the ECM, but it also has a clear connector that plugs into the "RED" ECM connector. It has a different tab, and wont plug into it.
My plans are to run a 700R4 which I have ready, and I would like to deleate the EGR from the ECM. But before I do anything like that, I must figure out what is necessory for the engine to start and run. I get totaly lost looking at the harness. All I want is (Bare Bones)! No EGR, NO AC, NO etc... Would I be better off just buying the Edelbrock Performer RPM kit with ignition box and just carb the thing? I would rather learn how to do this. I mean, programming can come later in the learning curve, right now I just need someone to push me in the right dirrection on what wires need to go where. Is there a book, DVD? I hate asking stupid questions, and I feel that this makes me look really DUMB
Anyway, thanks in advance for ANY help on where to get started.

Sounds like you'll want a painless harness to start with, at least on the car side of things. Im not certain, but the stock harness wont work with the 700R4 unless you cut and splice a lot. You'll save yourself a ton of headache and time with a painless harness built to your car/motor/tranny combo.

Thanks alot J. I did have a change in trans. I will be running my Muncie 4 speed. It's built, ready to go, and setting right here. I have ordered the flywheel, clutch/pressure plate combo already. So, now is just installing and fitting the engine and trans, and getting started on the EFI.

I have done a few conversions, and is not difficult.
There is a lot of work involved, you'll need to do a few modification but is not that hard.
If you don't want to go the hard way, find an engine with matching harness and PCM. Otherwise you'll need to modify the harness.
With a matching set of engine, harness and PCM you only use what you need and discard what you don't
Having the wiring diagrams is a must, so buy the Hayness repair manual
The muncie will bolt to the LS1 no problem
