Get some TRS couplers and some hosa cables - preferably ones with straight and 90° ends on either end since 90's generally work better on pads and cymbals.

Also recommend these ties, they work fast and are easy to add new ones - it really cleans up the wire mess

I've got 11 toms and like 8 other things running into a Mimic and a TD25 so I've got some experience runnign cables for this lol
