Question LS7 Wiring Harness/Doubts

Hello,

I'm from Brazil, and I got a LS7 to make a prototype.

So I have some questions about the engine, because I dont have the wiring harness, neither the ECM and the pedal.

The engine that I have is similar to this one,






Where can I find an ECM, wiring harness and the pedal to put this engine working?

Another question is about the Alternator, what alternator can I use in this engine and where to find it?



How can I put the TBI turned to the side of the flywheel, like in the picture above?

And about to check the oil level, what parts are missing?


All the parts that are missing I will import, so no problems about the store location.

Thanks a lot
Gabriel

Default throttle body

As for the throttle body question, all you have to do is mount the intake back wards. It can go on front to back or back to front. Factory Five is doing this with their rear engine kit car similar to the car in your picture. You can thank GM for making the intake manifold that way.

Gabriel,

We offer custom harnesses for the engine you are using in your project.

Let us know your specifications (flipped intake, length needed to computer mounting location, etc.) and we will build you a harness that fits like a glove!

We have made many of the harnesses for the Factory Five GTM cars.

Our custom harnesses are plug and play!
