Hey,
I have a 91 Firebird 5.0 TPI 5 Speed...
Sadly, my car / factory manual are in FL and I'm in WA Hoping to fly to FL in late June then UHaul it back to WA, 3,200+ miles...
Anywho, I plan to install (uh, pay a professional) a new American Auto Wire Highway 22 wiring harness, car alarm, custom wiring, etc...
I have an EBL P4 7730 ECM, VATS has been disabled / removed from the car. Engine / ECU and Engine Wiring work fine...
Just trying to plan circuits / amps, etc...

My first question....

What do I need to power from the fuse box to "run" the engine?

Fuel Pump - 20 Amp Circuit
ECM - Battery and Ignition hook up - 20 Amp Circuit total - 10 each circuit
Injector 1 - 10 Amp Circuit
Injector 2 - 10 Amp Circuit
ESC Module - ? Amps ?

Anything else?

How many amps does the ESC Module need?

Thanks, I'll keep posting questions in this thread as I progress.

It's not what the device needs, it's what size is the wiring supporting it. Smaller is always better if you don't know on the fuse.
I run the entire LS engine off a 40 amp supplied circuit and I run smaller fuses for the components than GM did from the factory for some of them.
You're probably fine with a 5, 7.5 or 10 amp fuse for the ESC

 

Those amp ratings were pulled from the diagrams I could find online / dynamiEFI, etc...
It's just a starting point...
Or more to the matter at hand, will it start at this point???

 

Ignition coil?
