So, I'm willing to bet the pins in the write-up are not right, maybe someone can back me up here:
It looks as if pins 1,2,5,6,7,9,11,12 are used on the new switch. After lining up the pin locations that Brunzo used and comparing my new switch, I assume he just mixed up 8 with 9 and 10 with 11. I'm a little scared but I'm gonna hook it up this way and pray I don't fry a brake controller. I still might take the old one off and check resistances on those pins compared with the new one, but I may be too lazy. I will report back with results.
