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?

now's the perfect time to upgrade to a proper boost gauge

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.

how about doing a write up with detailed pics.

how about doing a write up with detailed pics.

It was a on the fly type of thing, had both clusters side by side and wrote down each terminal pin on each plug on paper. Than checked both plug terminals against each other St204 and St205 noticed which wires had to be removed, and moved to different plug.
I was doing my 4th Gen 3SGTE swap and did the cluster then and there also wired in Dakota Digital SGI8.
Only wire you physically have to run is boost meter signal from ECU, other wires get cut just so they reach into different connector on cluster. Also rear fog lamp indicator is a bonus on J-spec cluster if anyone is into doing that to their Celi.

Advice I can give u is start with easiest things first like high beams, turn indicator, idiot lights, illumination, leave ones that u cant figure out for last it will be easier to do.
And I dont think one write up would cover all USDM Celis, Im not too familiar but think theres differences in options, for one I dont have ABS on mine or AT vs MT.
And its easier done than me sitting here trying to explain to you how to do it. Once your actually doing swap it starts to click, oh okay this goes here and that goes there type of thing.
your looking at about 2.75-3hrs with pulling everything apart to reassembly.

This is my 3rd cluster conversion I did.
Did my 92 Prizm, wanted that cool looking cluster with TACH from 92 Corolla DX I think, had nice OEM illumination rings around gauges (was ultra nice), swapped entire dash and all plastic trimmings from AE92.
Did my '90 240sx cluster, swapped in a '97 Kouki 180sx Type-X "digital cluster", was one of the easier ones as cluster harness unplugs from main body harness, so u can take it onto a table and do all work there, also with spare harness can be moded ahead of time.
