Need help wiring two HB's for coil tap

I have a Grosh Electraject with two HB's. It came wired in a standard configuration with no coil tap capabilities. Green and red wires of each PU wired together, hot wires to the 3 way switch and ground to the pot.

I bought a 2nd pick guard with switches, pots, etc., everything except the PU's. It is configured with a single volume, single tone with DPDT push/pull switch attached and a three way Tele type selector.

Current wiring is as follows:

Tone Pot - first leg has .022UF cap wired from the leg to pot casing, 2nd (middle) leg wired to the first leg of volume pot and the 3rd leg is not used. There is also a black ground wire soldered at the point where the tone pot and DPDT switch are attached which is soldered to the casing of the volume pot.

DPDT switch - attached to the top of the tone pot. Has three sets of legs arranged in a vertical configuration. The 1st set (bottom two legs) have solder residue which is where I think the PU's must have been wired? The middle two have a wire bridging them which is soldered to the switch casing. The top pair look untouched.

Volume pot - wire going from the first leg (also wired to the 2nd leg of tone pot) to the three way switch. A small resister and cap soldered between the 1st and 2nd legs, and a single black wire soldered to the 3rd leg and hanging lose.

With this information can someone tell me how to wire the PU's for a coil tap capability?

Please help. Thanks.

To coil tap you only need to worry about that DPDT switch.

It'll help a little if you understand what's going on. Think of it as 2 sets of three, each vertical row of lugs are the 3 lugs of a switch. The middle lug is the common. The outer lugs are activated as you move the switch either way. Lift up on the knob connects the upper lug to the middle.

So what you want to do is take the green and red wires (on just one pickup) and connect them both to the center lug. Connect the upper lug to ground.

Do the same for the other pickup on the other half of the DPDT switch.

Thanks Koko Tele. That makes sense, except that Grosh has rand a single wire from the housing of the DPDT switch and bridge the two center lugs together??

It must have worked because all the guy I bought it from did was unsolder the PU's. I can see solder residue on the bottom lugs (both side), so can I just use those in the manner you described for the center?

Thanks so much for the help.

There's always more than one way to skin a cat. Hard to tell exactly what he did before and why, and honestly, it's Sunday morning and I'm in a mood not to think too hard about it :-)

Easiest: just remove whatever's on that switch and clean up the lugs, and start with what I described above.

Fair enough. Thanks for the help.
