OK, good info but a puzzle at point 3: If red and green are indeed going to the same coil as they appear, and if they had been previously permanently joined as part of the standard hb wiring, then that coil would have been shorted out. I'm assuming that where the wires appear to go is where they do indeed go, not doubling back to the other coil on the other hidden side of pickup (id doubt it). The pickup manufacturers of the world had a meeting and agreed that between them they will wire their pickups with every possible inconsistent combination of red, green, black and white. Therefore the following link is of no use at all to us!: guitarelectronics.com/guitar-wiring-resources/humbucker-wire-color-codes/But the scheme will definitely work but needs a bit of testing, using a multimeter and/or tapping the poles. A multimeter on a resistance setting of 20k will let you check that red green is a coil pair and black white is a coil pair. Then, we need to test phase of each coil. Can you do this test? guitarnuts2.proboards.com/thread/4938/testing-phase-screwdriver-pull-testYou can use it to test the neck as reference, assuming white is hot, then work out which side of each humbucker coil needs to be towards hot and which to ground to get the same phase as neck. You cn do it with a cheap multimeter, or record into a pc sound card - see if that test makes sense. If not, we will make a guess and be prepared to change it Those pesky Pick Up companies are behind EVERY conspiracy theory :-( Well it appears that the meter says Red&Green share a coil and Black &White belong to the other coil of the Bridge Pickup. Also the coil nearest the Neck Pickup (the one that'll probably be the best to be active when the Bridge HB is in SC mode) seems to be the same phase as the Neck Pickup itself I hope this helps

Slowly getting there but not arrived yet...
Based on info so far, there are still 4 ways to wire up tbe bridge pickup and 3 are wrong!
So..phase tests. Reversing wires swaps phase. We start with assuming neck is the reference, with black to ground and white to hot.
Take the red green bridge coil. With red to hot is it in phase with the neck? Or is it in phase with neck when green is to hot?
Similar with black/white coil. Which bridge wire colour has to go to hot to be in phase with neck (with neck white to hot).
We already know that the red green coil is the same magnetism as neck. So we will be spinning tbe bridge pu 180 degrees, which does not affect any of this phase stuff. This is to get the bkack white coil as the main single, nearest the neck so neck and bridge combos are an in phase and humcancelling combo of opposite magnetic polarity.
Youd be welcome to drop in down here in Australia and we will sort this out in 5 minutes!

Ditto here in Liverpool England! ๐ OK I'll have an answer for ya in about an hour or so & again THANKS for all your time & knowledge ๐

OK it seems to me that when the Bridge HB's White wire is connected to the meter's Red probe then it is IN Phase with the Neck SC & that when the Bridge HB's Red wire is connected to the meter's Red probe then it is IN Phase with the Neck SC Really hope I've done this right cos I don't wanna mess you round! ๐

OK we can go with that! Based on those tests, the pu doesn't conform to the usual Seymour Duncan or DiMarzio colours, but it does match Peavey and a couple of others. It also matches Gibson but they don't make a blade pickup so far as I know. For the single coil bridge, in phase with neck, it needs the active coil to be opposite magnetism to the neck. So the bridge is physically spun 180 degrees, so that coil is also the one nearest the neck as requested. It may not make a big difference since the coils are close to each other though. If you find any issue with spinning it, still wire up with these colours to the lugs as shown. When you pull the phase switch, it will use the other bridge coil, and if you only have the bridge on, you can use the phase switch to hear the difference between the two bridge coils. All full in-phase humbucker when the blower is on Good luck!
