(NOTE: If you have a different color coded pickup then just hook it up following your coding to the pigtail inputs above.Clapton acquired this guitar presumably sometime in 1967. This can be verified with clip leads if you are skeptical. If you do not connect it like this, it will still work but there will be a noticeable power loss in the mid because of out of phase. the Neck is color coded properly.Ĭonnect Red from pickup to White on pigtail To rectify you have to forget about connecting proper colors to proper color and just give the board what it is looking for.Īgain note. So when I hooked up the pickups to the quick connect pigtails and observed proper color coding it actually put the pickups out of phase. (Note: This is the circuit for both of my 2013 LPJ's and a friends 2013 Studio with the same pups and QC board) So the neck circuit is looking for Red/Black as the positive and negative and the bridge is looking for White/Green. Neck - Pin 1 - Shield / Pin 2 - Black / Pin 3 - Red / Pin 4 - Green / Pin 5 - Whiteīridge - Pin 1 - Shield / Pin 2 - Green / Pin 3 - White / Pin 4 - Black / Pin 5 - Red The quick connect board and connector have these color codings. I was installing standard Gibson 490R/498T's which do not have quick connect connectors. Green - lower coil finish (connects to white in 2 conductor installs) White - upper coil finish ( connects to green in 2 conductor installs) Standard Gibson pickups with 4 conductor capabilities have 5 conductors (including screen or shield). Gibson changed the color coding on the connector for the Bridge pickup and that caused the pickups to be out of phase when installed properly (color to color). You can connect them in this manner and both pickups work but the middle switch position has "noticeable" power loss. The problem was the new standard pickups did not come with quick connect connectors so I assumed you can just splice them to the existing pigtail and all would be fine. The LPJ has the new quick connect board and connectors. I recently found an issue when trying to install a new set of Gibson 490R/498T pickups into a 2013 Gibson Les Paul LPJ.
Those are 4 pin connectors, Gibsons are 5 pins, just change the suffix to 0500 from 0400. Maybe find an adapter for USB and splice to it. After taking a second look, those look like PC motherboard connectors.
Thanks to the original contributors for this information. Here's some reference information on the quick connect plugs and wiring that Gibson uses on their guitars with a circuit board in the control cavity.
