What wires need to go to the “B” and “E” slot? They are labeled “Ammeter” on my wiring diagram, but my Kwikwire wiring harness does not have a wire labeled “Ammeter” so I left the slots empty for now. Also, I wasn’t sure what to put in the “K” slot because it was labeled brake light ground on my wiring diagram, but my wiring harness book didn’t say anything about it. Thanks!
