brake lightrs

[mehoff400]

needing a little help... the previous owner rewired my truck with a kwik wiring and the rear turn signals don't work correctly as they both flash at the same time and i think i chased it down why. he splice the 2 wire brake light power and brake light switch together and ran that to the tail lights. from the research i have done it looks like it needs 1 power to the switch then 1 wire to the turn switch.

and then i am guessing it would get brake light through the turn signal wires?

if this is correct what wire would i tie this into on the turn signal switch?
