what lugs do I hook up a remote starter up to?

[Steeveedee]

Depending on how long the wires are, I'd hook the cable clamps to the starter's "S" terminal and the battery positive post. Reason being that it's possible for those clamps to turn while you're working, and ending up with constant cranking when they short together, and you might not want that. Easier to pop the clamp off the battery, up where you are punching the button.
