You won't be disappointed going with the manual pump! Are there anymore cheap manual pumps floating around your end, I'm after one myself, but they're rare and people want mad money for them!
Changing the pump isn't too difficult. Disconnect all rear injector pipes, two of the ones to the front of the engine will need to be removed completely. Underneath the pump towards the back of the pump, and side of the block is a mounting bracket, two 12mm on the block side and one on the pump body. These need to removed along with the bracket. Two 12mm nuts on the front side of the pump. One is easy to get to. One is on the inside in between the pump and engine. A good side spanner works or a small ratchet. Theres piece sound deadening in this area which needs to be removed to gain access. I also pulled out the vacuum line for more room.
Now the front side of the engine. Remove the fan shroud cover, 4 x 10mm bolts on each corner. Bottom plastic piece just snaps out of place. Remove the timing belt cover (easy). Now you don't have to, but it's always best to align the engine TDC. Now, if you're lucky these next steps will be fairly easy. No need to remove the belt or anything. Undo the main pulley bolt on the pump, I think it's a 24mm. A big goldish nut. Don't undo it all the way out. Using a big hammer knock give the bolt a good thud and see if the pump moves back out of it's spline. It either will, or it wont' So if it doesn't move on to these next steps. You'll need to either make/or buy a puller/pusher to push the pump out of the spline. You will use to pulleys bolt holes to do so. I had to take my rad out to get some more space made for the tool.
Remember to put back the front oil seal on the pump shaft. Regarding the cable, you'll need to make that up yourself or source the bits.
