Thanks Flak, appreciate your detailed explanation.
No worries mate.
no need to remove the alternator can run them through the area they need to go without any real hassles
Yeah, you don't have to remove it. I meant you just unbolt it all except the positive and negative wires on the back. I just unbolt it and sit it back a little as it makes it so much easier swap them, saves trying to shove the boots through the hole underneath it. Easier to make it neat. Run the wires under there and chuck a little cable tie on the drivers side just as they come off the manifold to keep them neat.
Oh and just in case you didn't realise, you have to remove the engine cover and slip the belt off the alternator pulley, or the idler first, whatever is easier. Draw a pic of where the belt goes first, just in case it falls. And while you're there, you might as well take off the plastic intake tube closest to the throttle body, and spray a little carby/throttle body cleaner in there, and wipe the butterfly, especially the back. 10 seconds of spraying all up will be heaps. It will make it a little harder to start the first time, then run a little rough, just rev it a bit and it'll be fine in 10-15 seconds. And finally, since the belt is off, inspect it for cracks, and spin each pulley individually to see if they are free, smooth and silent.
Don't stress if you break the plastic lead holders, they often break. Try pry them open carefully with a small flat blade screwdriver. Just take your time, be observant and neat and you'll do an awesome job. Let us know if you have any more questions or get stuck though.
Hm, that was kinda a lot, but yeah, take your time and think about it, and you'll do great
