Got truck with code 123. Access 1 not seeing input. Replaced access one same issue. Getting 7V when no volts are supposed to be there. Continuity from switch wires to access 1 & 3 is ok. Thinking there's a short somewhere, but can't pinpoint. Checked splice 6, still uncertain how that plays a role. I'm getting battery voltage when checking voltsge to frame. I leaning towards battery voltage leaking thru case. If anyone has experienced this or has any advice, please share the knowledge.

Thanks
