and pretty much everyone that has completed it says its easy.
i’m finishing up an sr swap right now and the only problems i’ve had were caused by a butchered harness that i had to rewire, i had the normal modifications that you have to do with any harness done in like an hour, the rest of it was wiring up stupid shit like a different igniter because one of the sr plugs was cut off for whatever reason.
if you have ever soldered before or feel like learning how to solder the wiring is not hard at all, you print off the heavy throttle sr swap guide and follow what it says, it tells you to connect this wire to this wire, this wire to this wire, and its pretty hard to mess up.
good luck.
