ok here is a write-up with pics/diagrams
here are the wires i found on my 4.6
**All wire connections should be soldered and wrapped in electrical tape**
i opened up the wire loom on the main harness coming out of the passenger side ffrom the EEC, and cut all 5 wires and proceeded to install the COPs onto the intake manifold.........you will need some metric screws m5 x 0.8 pitch, 20mm long, in case you dont have the ones that come on from factory........you can get some at Ace Hardware, or i believe they are like $1 each and come in packs of 4, which you can get from Dan Newman.........here is where i opened up the main harness to make all connections:
although i didnt get a shot of the wires inside the main harness, you shouldn't have any trouble finding these wires.
moving along........first i soldered two wires to the ignition wire.........one long enough to reach the coil at cylinder 1, and the other long enough to reach cylinder 7 (routing this wire behind the manifold)........then i wired up the first pair as follows:
**A half-circle on a wire crossing another wire means no electrical connection is made**
this is what one of my COPs looks like with the connectors i used:
now onto wiring the second pair........since there is already power going to the first coil, i spliced in a very short piece of wire to also power the positive side of coil 3:
to wire up the 3rd pair, i powered coil 7 first with the second wire i soldered to the ignition wire at the harness, then went along to coil 4:
i then did the same thing to power coil 8, as i did to power coil 3.....spliced in a short piece to the wire that powers coil 7, then went along to coil 2:
and there you have it.........just gotta secure all the wires neatly with electrical tape or plastic ties and cover it up in plastic wire loom, and tape up the main harness, and you've just saved a ton of space........this is how the driver's side looks like with all COPs in place:
a before shot of my engine bay:
and now after:
as you may or may not notice, the power steering reservoir is holding on to dear life with some plastic cable ties (LOL), since this was just a temporary fix. You will need to get the support bracket from a COP-equipped Ford 4.6 vehicle and you might have to work with it to get it to work but it'll work it does bolt up with some modification.
a couple other things i should cover.........you'll notice that the noise-capacitors that are bolted to the brackets are not there.........i didnt notice any ill effects with them removed, so i chopped them off and left it that way
you will also notice that the red/green vacuum lines that also went to the passenger side bracket and connect to the EGR vacuum regulator solenoid are not there..........what i did was chop off the connector with a few inches of slack on the wire and spliced it in to the wires at the main harness........i then cut the red and green hard vacuum lines right around the passenger side fuel rail, and used rubber vacuum hose to route them to the vacuum solenoid now secured at the rear of the engine bay on the firewall.
and that about covers it folks.... also one more thing i recommend using the piggy back type wire splices, i don't have a picture but they just clamp onto the wire and provide a clean splice.
