i pulled a lt1 out of a 94 formula for my 86 iroc and i need to know what wiring i need to pull out of the formula to complete the swap besides the harness connected to the pcm and engine i already got that out,i need to know asap cause the formula is taking up to much space and i need it outta here asap,any help would be greatly appreciated,thanks in advance,joe

 

Thats all you need!

 

i dont need the fuse block under hood drivers side front?or the metal boxes under the dash passengers side? the boxes had some wires going from it thru the fire wall and into the pcm thats why i ask,thanks,joe

 

You dont have to have the fuse box some say it's eayser though.

 

so what about the harness that comes out of the pcm and runs over to the fuse block? do i just cut the harness a couple feet away from the pcm and wire it in to the 3rd gen fuse box?sorry im really lost right now ,im not real experienced with this much wiring,thanks,joe

 

what about the aldl?should i pull that out to?what all wiring do i need under the dash?
