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

OMH meter between white and brown should show not-connected or thereabouts (ie no continuity)

with the gauge ON =
OMH meter between white and black should show not-connected or thereabouts (ie no continuity)
OMH meter between white and brown should show 0 ohms or thereabouts (ie some continuity)

if we can at least establish that baseline then we can move forwards.

^ all assuming you have DFS unlinked, FS0 linked?? and power to the HFS3 ...

Also FYI a reading of '0.L' implies NO continuity, it's not the same thing as 0 ohms...

Thanks for posting and help with the connections.
