Welcome. Which pickups? I'm guessing the humbuckers but...

Link is to Google Photos and embedding them here is a PITA. Link has two hand drawn schematics and two pictures of the control cavity from my '71 JS II which has a serial number about 2,000 higher than yours.
Not sure what constitutes "any and all information" but... This is off the top of my head and subject to correction from folks with better memories.
The slightly asymmetric double cutaway shape of the JS first appeared circa 1970. It was discontinued circa 1977. There is a guitar with the same body shape - S-100? The earliest JS IIs has some pickup variations. We have seen the JS body with two Hagstrom Bisonics and with a neck Bisonic and a different Hagstrom PU that doesn't really have a name. These variations are all in 1970. There have been a couple examples from the late 1970's where the body is a JS but the pickguard(!) pickups and controls are those of the successor model, the B-302. By 1971 the pickups had standardized to a pair of Guild Humbuckers. There was a single pickup version (JS I) and there are some stereo JS II's and some long scale (34") instruments as well. Circa 1974 there were some models with carved oak leaves and acorns on the top. There was a previous bass, with a different shape, called the JetStar. The JS and the JetStar really are two different models but even Guild called a couple of JS basses JetStars as late as 1974. I have no recollection of what wood was used. I know of a black, natural and walnut finish but there were probably others. In 1971 the case was a separate item and the case Guild sold you was a rectangular case, typical for solid bodies.
Lots of discussion, especially concerning the "deep/hard" switch, often inaccurately called the suck switch. I attempted to explain the circuit and was politely, but firmly told I didn't know what I was talking about and was corrected. If your search fu doesn't work and you are interested I'm sure someone can find some of the discussions.
