M38a1 flasher wiring help

[mitchell]

So i was trying to get my signal lights working on the jeep but the contacts in the plug where all sizzled. I put new ones on but forgot where the wires go onto the flasher box. Could anybody tell be where each of the A, B, and ground wire go? thanks. Also i believe the flasher is fried so where can i get the original type of flasher box in canada?

thanks
