ok i am getting closer to doing a turbo swap in to my 87 gxl, and i was going to being getting a haltech e6k pretty soon. question is could i use the n/a harness and buy a haltech with terminated harness for an n/a and use it now until i can complete the swap in a couple of months and then use it and retune it for the turbo engine?
or am i just better off getting a haltech with turbo II terminated harness and waiting to complete the swap.

also this might be a dumb question but, will i even need a tII ecu if a run a haltech?

the stock harness goes into the garbage. you use the haltech one.
