Mitsubishi EVO (USDM) wiring diagrams for HFS-3 (all US models)

[Chriswolf81]

Hi Richard,

I'm confused: the diagram on this thread for Evo x tephra alt maps uses the black wire for failsafe ground with resistor, but the link you posted to Evom has the brown wire used for this. You sent me a diagram via email last year using the brown wire. My failsafe/map switching is not working. I used the diagram with the brown wire as the ground.

Please help very frustrated.

Thanks
