I'm thinking that my soldering iron takes too long to get everything up to temperature, but I can have a bash at soldering the covers. Swapping them about is a good shout.
The Epiphone/Pearl pickups have two wires + shield. The start and end of both coils are nicely demarked with a metal lug/eyelet (I think the same thing was used on the WRHB I previously showed on here). The first coil is soldered at the coil-end eyelet to the brass baseplate with thin, un-insulated wire. The start of this coil is connected to the end of the second coil with a short white jumper wire. A second white jumper wire starts at this eyelet (end of second coil), traverses the length of the coil and runs down the hookup cable. A second, red, wire runs from the start of the second coil, and the screen for the hookup cable is also soldered to the baseplate near the start of the second coil. Between the screen and the white wire the DC resistance was half of that between the screen and the red. Not a full four-wire configuration, though setting one up would be easy. I don't like switches that cut the output from a pickup as I tend to run a fairly 'set and forget' setup and don't want to be worrying about the output dropping. As such I deleted the white wire when I re-wired the pickups.
I never checked the DC resistance of the Aria pickups, and I only took them apart to rob the hookup cable (I bought some of Ebay that turned out to be twin audio cable).
