<<< that is the bass which is going under the knife today!! i have done very minor rewiring before, things like swapping pickups etc. i currently i have two switches - one for active passive and another toggles between parallel and single coil modes. When the bass was being made, i wanted a mute switch and the pdf along with my pickups offers 3 way coil tapping ie - series/parallel/single. I also wanted the active passive toggle to be on the volume knob as a push-pull pot but we were on a serious time dead line and did not have those parts at the moment.. so am going to get to it today! maybe i will go 18v as well? i am still not sure about that. your thoughts on any of these are welcome, although am going to open it all up about 6 hours from now. bartolini dual coil pickups and aguilar obp3 preamp
1. i will unsolder the leads off the active passive toggle switch and volume pot and re solder everything to the new volume pot. schematic provided by aguilar, i just double the dpdt bypass toggle switch "on top" of the volume pot dpdt lugs. and add the mute/kill switch to the "bypass" switch. modified schematic thanks to @line6man am not installing a tone pot right now. so just the kill switch. maybe i will check and make sure this works fine?
2. take out all the pots and electronics to save them from the sawdust. Spot, mark, aim and drill an additional hole in the bass for the new switch. now i have 3 switches (kill switch, and one coil tap switch for each pickup)
3. rewire the pickup leads according the bart pdf
4. do i want to go 18v? i play fairly softly and i like to not dig unless needed and my pickups are not much "hot". my battery is always running out as i spend a lot of "plugged in time" aguilar says at 18v i get an additional 6db. now that might overdrive some mixer type input stages but if it really happens too much i can go back to 9v but i do not think i will need to. the only thing i do not like is that i will always need to carry and change two 9v batteries everytime. right now i change my batteries every 30 days, 10 hours a day brings it to around 300 hours of play time which is byebye time according to the aguilar manual which says battery life is 320 hours. so maybe now that i have everything out i will solder another battery clip in series to have 18v operation.
i do feel i should have gone for a 4 band preamp with separate hi and lo mid bands on my bass but i do not want to drop 300$ on a mike pope flexcore right now! anyway thoughts? i have to drive 2 hours to my friend's house who is good at this stuff and get him to help me out! he recently done pretty much the exactly same "operation" on his passive warwick rockbass and it turned out very very clean and factory like so yay!
mute switch schematic - (line6man said if the mute switch makes a click noise i can add a 1-5Meg ohm resistor between each throw, i do not understand where i should add the resistor(s).. can someone add it to this image or explain it to me, else am hoping my friend will know)

things i think i will need -
1. soldering iron, solder, drill - my friends has this
2. extra wire (have to go buy it, what kind do i really need?) and battery clip from the shop as well
3. pushpull pot, two 3-way switches. got these!
am not sure if i will need anything else, any thoughts?
