So I followed the 3d diagram for 4 way from 1st page, with 470k resistor to hot bridge single coil on pull tone pot, as both tone and volume are 500k. Took me few hours, as the most I soldered before were 2 wires on a Pentax camera solenoid (well 4 wires since i repaired 2 cameras). Deciding what to wire first, what wire to use, man, was tough first time experience, but in the end hoped for the best and pushed all back under control plate. As my guitar is a cheap Jet Guitars JT-300 (my son loves the neck by the way), had to enlarge the holes for control plate and the one for jack. Switch was fine, fitted without problems. One other challenge was the pickguard, as there is no official one for SH, and the tele Fender ones, while having the same number of screws, only 2 holes are on the same position, and the curved space for control plate is smaller. So I bought 4 boards 25x25cm (enough for a tele pickguard), 2 forex and 2 some harder plastic, 3mm. Since I don't have any electric tools or workshop, had to use a regular cutter, the forex board is not that tough. Neck humbucker cavity is rough, well I guess could and should have done a better job, but that's that, it is first try, I will try later on to do better. Went for a dirty look, don't know how to call it, probably ugly would be a fair description, but it had to do since all i had was a black permanent marker, some white paint and isopropyl alcohol.
Now for the is it working part - have continuity where I suppose to have, all 4 positions work, had a problem with tone knob doing nothing, open it up and saw that when i pushed the capacitor metal was in contact with pin 2, so i spread it a little further. Now it works. I'm waiting for my son to test the sound, probably the pickup height is the best way i have to balance a little the sound. 2 pictures attached, one with cavity shielding, the second with the finished-unfinished horror Thank you for all the info provided, I think I learned a lot from you guys!
