Hey guys,

Not sure where this thread belongs but if a mod wants to move it to the right spot go for it

I am currently doing a 5.3 Truck engine swap with the LS1 intake into my 84 corvette and am having trouble with the type of engine harness and ECM to get. I am electrically inclined to do the splicing and to figure out where wires need to go and all of that stuff but I am not sure which harness to get. Should I get a truck harness and splice in the pigtails for the injectors and what ever else needs to get spliced in or should I get an LS1 harness from a camaro/firebird or get a Corvette LS1 harness and modify it so its set up for a cabled throttle body?

And ECM. I need one to get flashed, correct? And I also heard I have to turn off some of the stuff on the ECM. What stuff do I need to turn off and how?

Also I heard that some years are weird, like the 98 camaros. Why is that?

Any help will be greatly appreciated
Thanks
Cory

The only thing I have heard about 98 cars is that they are harder to tune.
