Thread: How To : NX1600 Digital Cluster Into A B13 Se-R

Before I Begin I Want To Thank Few Members Who Had Done Previous How To's . SinisterSentra91 & M0J0 .

First Started Off Using The Diagrams That SinisterSentra91 Posted .
Here's The Link For More Info On His Thread (http://www.sr20-forum.com/audio-electronics/38323-digital-gauge-cluster-info.html)
But I Wanted To Know What The Wires Were .

So M0J0 Posted What The Center Plug Was On The NX1600 Digital Cluster.
This Is What He Posted For The Center Plug(Black 12 Pin Plug)

The Pinout Of That Plug Is As Follows:

1...7
2...8
3...9
4...10
5...11
6...12

1 - Speed sensor positive (but doesn't really matter)
2 - Illumination (not sure whether positive or negative)
3 - Speed sensor negative (but doesn't really matter)
4 - Illumination clock
5 - Tachometer
6 - Illumination (not sure whether positive or negative)
7 - Ignition
8 - Temperature
9 - Fuel level
10 - Ground
11 - Speed signal to ECU
12 - Battery for clock (so the cluster can "remember" the time)

This To Me Was My Foot In The Door To Begin My Wiring Process .

Than After A Few More Post I Bumped Into This Diagram Which Is The Prefect Solution For The Labeling Process .

Now Using This Diagram :

Edit On The Diagram Pin 34 Is Brake


Once I Had All This Info It Became Way More Clearer & Simpler To Me .
So I Made This Diagram Using My NX Cluster & The Center Plug M0J0 Posted .(Using The 93-94 Se-R Diagram)



Now I Begun My Process In Getting This Wiring Completed .
After Using Both The 93-94 Se-r Diagram & The NX Diagram Labelled Where My Wires Had To Go .
I Also Noticed While Labeling That Some Of The Illuminations Are Labeled With R/Y or R/B

When I Did The Labellings , My Illuminations Were The Last I Did Since I Had (2) Red/Yellow & (2) Red/Blue I Just Grouped Them By Color
There Are (3) Ignitions (Yellow Wires) I Grouped Them Also

This Was My Final For The Wiring Process

I Hope This Was Alittle More Helpful & More Understanding Where Everyone Can Do & Enjoy A New Modification On Their B13's

my nx 1600 digital cluster is a bit different. my yellow plug has 13 wires, my black plug has 12 wires, and my white plug has 9 wires! im so confused! just picked this thing up and want to install it!!

u sure u got 13 wires in the yellow plug . recheck that . what year did your nx cluster come out of .

Noticed the link to my picture expired.

interesting if i ever do this, thanks for the wright up

It looks scary, but it's simple as can be once you get in there.
