So I got my ISSPRO dual EGTS and FP ready to be wired. I have all the wires run and the plugs for the gauges wired up. I want them to be able to dim with the dash lights. . . I have the gauges lighting up, but they wont dim. How did you guys do it? I have the ground run to the cross-member under the steering wheel. I have 2 fuse taps for the pos/neg wires off of the gauges. I tried a few different combos couldnt figure it out. Any advice appreciated
So I found a page on riffraff. Said to use a T tap for the dimmer and then the radio fuse which is what I was using. So I ordered those I will just run them full brightness for a few days

They also recommend a potentiometer in the line to the LED gauges so you can adjust them to match the factory dimming. You only have to set it once, I just left mine under the dash.
I recently added Autometer factory match gauges in a gloshift pillar mount, all wired to the dimmer for back lighting, the trans temp & the egt gauge dim just fine but the boost gauge stays bright!
