GT4 Help, GT4 Cluster Options

[shai]

Is there away to get my turbine gauge on the GT4 Cluster working? Do I have to link another wire towards the ECU to get it working or do i have to get an GT4 dash harness?

I wired my GT4 cluster in with out any issues, on my 4th Gen 3SGTE I tapped in to Map sensor signal wire coming into ecu plug. Boost gauge works fine, reads vacuum under idle and I see almost 1bar at WOT I know Im maxing out the gauge at last mark. Makes interior nice and clean, cant even tell its boosted. If you got the GT4 cluster already than take the time and wire it in, I think its much better than some cheesy a$$ gauge.

And its ether boost meter or boost gauge->havent heard anyone refer to it as turbine gauge, turbine is the hot side of turbo, your actually reading compressor side or intake manifold pressure..FYI dont want to come off as a prick.

Read the printed circuit board and see which wire is signal for boost meter run that wire to ecu connector and tap into that wire on harness it the 5v reference signal wire........simple as that. 2 other wires are power and ground which comes off of the cluster it self.

To get the rest of the cluster working you'll have to cut and lengthen some of the wires and bunch have to be repined.
I did the obvious ones first like "idiot lights" pulled out bulbs and traced every electrical trail back to connector, wire down on paper, check with your stock cluster and ether repin/cut/lengthen accordingly.
