Baja S1 Wiring (Lollar 3 Wire)

[Hallski]

I picked up a used and modded 60's Baja last week. The owner had changed the neck pickup to a Duncan Rail HB, and I have ordered a Lollar 52 T Series to replace it and it should be here Friday. There's obviously much discussion here about the S1 and the diagrams to go with it, but I haven't really found my answer in those posts. I want to make sure I know where to reconnect the single coil to take the place of the humbucker they added and get the stock S1 switching back in order.

I'm sure this is rudimentary, but I've never done any 4 way switching wiring, so any help is appreciated!

Current wiring. The black and green wires on the S1 Volume pot are the humbucker wires. The red and white are tied off.


These are the Lollar wiring colors.


Using this wiring diagram, which should go where?

This is the Fender Baja 60s wiring drawing which may help.
The Lollar 3rd wire option is to ground the cover separately from the coil and is the yellow wire in the Fender drawing

@Tuxedo Poly great, thanks! Very helpful. I was going to find a two wire pickup and just do a third wire mod, but when I ordered the Lollar, they gave me the option, so I figured it would be best and easiest for them to just add it.

So in my case, the black wire on the Lollar is the ground, and that will follow the path of the Fender Yellow wire on the diagram. On the Lollar, my white and yellow are hots, does that mean I should have the white from the Lollar follow the white from the Fender diagram? And then the yellow from the Lollar becomes the black from the Fender diagram?

It may be easier to visually identify where the wires are soldered or contact Lollar and ask which is which.
The yellow wire on the Fender diagram is soldered to the pickup cover tab so visually check which Lollar wire is the same.
The other 2 wires are soldered to the pickup eyelets and are usually white - hot and black - ground. The Fender drawing uses this convention.

Got it, pickup will be delivered today so I'll have a chance to look at it and check it out. I guess my ultimate question is, does it matter which wire goes to which eyelet? On the Lollar, theres the ground and the two hot wires, but each hot wire is labeled either Non-RWRP or RWRP.

Emailed Lollar this morning about which leads were what, and they quickly got back with me.

So, it will have 3 wires; white is hot, and both blacks are grounds (from the pickup and pickup cover).

I also found this diagram that should be pretty helpful. Looks like the yellow wire on the diagram will be the white wire from the Lollar, and the black and green wires on the diagram will be the two black wires from the Lollar.

Something like this should work

That worked! Just got the pickup in, all positions are working. Had to take the strings off to get better access to run the wires, and I have some fretwork to address before I put new strings for a true test, but tapping the pickups in the the S1 down OOP positions seems to be doing what it's supposed to in terms of output as compared to tapping them in the S1 up position.

I really appreciate your help, and I'm sure there will be others that will reference this thread in the future who will be helped as well!

I recently had the bridge pickup replaced on my 50s Baja, and now the S1 out of phase sounds are present when the S1 button is in its default position rather than when it’s in the pushed-in position. Any idea how that happened?

I just had the same issue! Was going to come back on here and post about it. I put a Lollar in the neck, and I followed what was diagramed above and from other sources, and it was in phase with the S1 switch DOWN, and OoP with the S1 switch up. See image below: I had the hot going to B2 and the pickup ground going to B4. That needed to be reversed, so now the hot goes to B4 and the pickup ground goes to B2, the opposite of the diagram's I was shown.

It works now in the correct S1 switch position, but I have a reverse ground issue as a result I'm thinking. I need to figure that out yet.

I revived this thread just now, it addresses our situation a bit; https://www.tdpri.com/threads/s1-switch-and-dimarzio-question.1077853/post-10822698
