Routing for spark plug wiring ?

Routing for spark plug wiring ?
I'm about to replace my ignition wires, however the PO put some 8mm Denso wires on it, and honestly, i don't know if it's just bad from the factory, or if they made a mess of the routing.
Does anyone know if there is a reference for how to route the wires, including the clip points?
Or, if anyone still has the factory wires/kept the factory routing when they replaced?

Oh excellent, thanks, just what i was looking for.
My NGK leads will arrive this week, the Denso's on there right now are way longer than in your pictures, it's a massive mess :(
They're also covered in oil and some other gunk, got some work to do in there.

Ahh, yeah, all i can find is a single reference to older Rangers having the coil pack oriented 180 from this.
Though yours being only a '99, i would have thought they'd already be this way round now!!
Anyway, i pulled all the cable clips out/off last night and set them aside for cleaning, the drivers side bank were all fitted backwards, holding the cables against the engine, and the cables were twisted round the back of the engine.
On top of that, at least one wasn't setup correctly and couldn't be mounted on it's post as it was pulled too tight, causing it to sit up about 4 inches from where it should be.
Anyway, there are *no* guides or pics anywhere of HT lead routing, which i find a little weird, but i already thing Ford's routing is terrible, i mean, some of these cables are hella long, for no good reason at all!!

Things were changes quite a bit when Ford went to the plastic upper manifold.
Obviously Ford had a way of installing the wires at the factory, but it's not critical.
One wants to keep the engine bay looking as tidy as possible though.
Start with your longest wire and the furthest distance, using the clips along the way that's closest to the path to get to "that" spark plug.
Keep going with next shortest wire until your done.
If a wire is too long, take a longer path keeping to the clips as much as possible.
Be carful not to let a wire rub up against things that will eventually cause chafing.
New cars are much simpler, no more coil pack, each spark plug has its own coil, so all there is are wiring loom connections up to each individual coil.
It would look similar to the loom going to each injector.
When I put my wires back in after the engine rebild it took a 2 or 3 goes to get right, or at least to something that looked neat and tidy.
