I have two choices in wiring up the 93 Corvette LT1.
I have a stock ECM and wiring.
I also have an MSII.
Both will be batch fire.
Stock gives me a known tune, MS requires mapping my own.
Stock seems to have a lot of unneeded wiring.
I know the LT1 is now "Old" but it's what I have now.
I don't see a dedicated thread for LT1 Second Gen.
Search did not locate the wiring help I really need.
Any wiring help would be much appreciated.
I will also be doing one probably unusual modification.
I intend to create a plenum over the intake that will simulate the original carb and air filter.
That allows me to make my cowl-induction hood functional and restore some semblance of a 68 SBC 327.
Since it will only direct dry air it doesn't have to be fancy.
