I'm Awesome
So I plan to do a LS swap in the near future on my 97 k1500 it has the 5.7L vortec in it now with a 4l60e. Where I am u can get a somewhat low mile 5.3 with harness and ecu for a little under 1000. I have a pretty good understanding of how to make the swap work physically and mechanically but pretty stumped as to wiring. Do I need to overhaul the old computer and harness and just use the new computer and harness? How will I get my gauges to work? Will the new harness be able to electrically run my old transmission?
