Easy as. Just have a quick look how the old one connects to the acc pedal, theres a funny little push in type plastic retainer that the cable moves through. You'll see what I mean once youre under there...
Yeah just tight is fine. Adjustment is on the Throttle Body end, the 2 17mm(?) nuts on the threaded section of the cable can be wound back or forth to get correct tension. You'll figure it out, if its idling its head off its too tight...lol.
