Scheel-Mann Seat Heater Wiring Problem (1 Viewer)

[Greyota]

All,
I need some help figuring out why my seat heater isn’t working correctly. There is something not quite right with my wiring.

The problem: I’m not getting heat to the bottom seat pad on High.

Here are the voltage readings I’m getting when selecting Hi or Lo with my switch.

The only modification I did to the Scheel-Mann harness was to clip off their switch and replace it with an RX300 switch. That diagram is here:

Any thoughts would be great. Thanks.

Here’s the whole diagram that shows where power is being routed through the Scheel-Mann harness.

2/12/2024 Edit: I found that the initial info I got from Scheel-Mann was actually incorrect - it wasn't heating correctly. On the Scheel-Mann harness, the Red/Blue = Low and the Red/Yellow = Hi. So I flipped them as how they are shown in the diagram below. #2 Red/Green connects to SM Red/Blue; #3 Red connects to SM Red/Yellow.
