I did an S4 n/a to turbo swap and kept my stock dash harness and gauges. Everything worked for a while then suddenly the four gauges on the left (gas, oil, temp, and battery) all simultaneously shut off. I've checked all the wiring and fuses I could think of. The tach and mph gauges still work perfectly fine.

Suggestions anyone?

 

The tach and all those other gauges are powered from the same METER fuse. There's no rhymn or reason for those others to have gone out. I'd say it's combination meter related somewhere in the combination meter.

Maybe something to do with one of the two Round plugs that attach to the combination meter. Even that idea is a reach since most of those items share the same plug as the Tach.

 

Yeah it made no sense to me either because they were all working for the longest time. I'll check it out, though like you said still a stretch. It's annoyingly baffling.
