Kouki 180SX "Type X" Cluster Help

[Treyz]

OK so I pretty much mapped out the cluster to the original cluster. Now whatever wires were left over I color coded them. Everything works fine but this is my problem now....

- Tach reads higher than what it really is at and is a bit jittery

- Speedo is reading faster than what I'm going (i.e. It's reading at 120km/h [which is around 75mph] when I'm only really doing 35/40).

- Heat is reading to top when its not overheating at all.

Any ideas what it woud be or wiring info would be greatly appreciated.

Thanks

Not knowing ANYTHING about this "Type X" cluster, my first assumption would be that the signals from the cluster are too "hot." I mean, in any cluster, the needle motors are controlled by a variable electronic signal that is determined by a sensor somewhere. If the "Type X" cluster is set to read a lower signal, then the normal signal from a cluster that feeds a higher signal will cause it to read that way.

lol .. I realized it was the dumbest thing that I overlooked .. wont go with my car yet lol .. its a SOHC and the cluster is a DOHC .. but getting the DOHC swap done within the month.

Here it is BTW ..

.. its a SOHC and the cluster is a DOHC ..

Yeah, that'll do it.

Boy do I feellike a dumbass but better me finding it out rather than someone else telling me lol ..

[Treyz]

so now that the speedo and tach problems are taken care of, I still have a problem with my gas gauge not working and the thermostat gauge reading that the engine is overheating when it is not at all. Does anyone have info on the wirng for the cluster????

[Treyz]

BUMP

Anyone?

I know its an old post but I usually dont leave the SR forum.

You need to use the S14 SR or KA speedo to get speed right. You need to have a DOHC engine for the tach to read right. You need an S14 SR or KA temp sensor to get the temp gauge to read right. As for the gas meter let me know if you still have issues with it. I have the meter running in my car with no issues. All warning lights working, etc.

WOW! That looks amazing!

If you don't mind me asking what is required to run that cluster?

Also I noticed you have a digital climate control working.

I could really use some tips, if you feel like emailing me [email protected]

Thanks in advance

To run the cluster you need:-Wiring pigtails for the kouki cluster (or some other similar plug ie late 90's maxima cluster plugs, etc.)-S14 Speed sensor-S14 Temperature sensor for the cluster (single wire sensor)-A DOHC engine for the tach to read right.-Create a conversion harness using the kouki cluster plugs and the USDM cluster harness.

The wiring conversion is a lot easier with the JDM wires because quite a few of the wires are the same in color.

As for climate control, its been a year or so so I dont remember much but it should be something like this:You need the JDM S13 interior wiring (basically the heater related items: blower, sunload, mode, etc)The wiring for the digital climate control is in a subharness so it is pretty self contained, all you really need to do is find out which wires are the powers, grounds, illumination, and some of the AC crap (I didnt use AC).

You will need to use the JDM resistor box. Sunload sensor. Ambiant temp sensor. In cabin sensor. There is a long sensor that goes into the AC core, I dont think its necessary.

You use the USDM mode door motor but I think you have to repin the JDM connector opposite or something.

You need to make a custom mount for the heater door motor and it needs to be EXTREMELY precise for proper function. One of the problems most people forget with the heater door motor is that the amount of travel to open the USDM heater core from full hot to full cold is shorter (or longer, cant remember) than the Japanese motor is able to stroke. So you may need to add an extension piece to get the door to open and close fully. Also make sure before you bolt anything that you have the motor moving the door in the right direction. I got the climate control in and running in under 3 hours, except that when I turned it to full cold the motor moved the heater door to full hot. Takes time to redo these problems especially when you have already put the dash back on.

You do need all the sensors plugged in for the heater door motor to move.

Do not get the kouki 180SX climate control or wiring, it is not wired into a subharness, the climate control wiring just flows into the main wiring harness like the US 240SX.

I cant remember much else at the moment. I know I have the wiring diagrams somewhere. I would suggest getting the JDM wiring and not doing the frankenstied method of making it yourseld simply because it is a lot quicker. Heres a bad pic of the harness you would need out of a front clip...

Haven't been here in a while but I'll give you an update. I figured out the gas gauge issue. Basically had to take off the meter from a USDM one since the frequencies are different.

I have an early S14 KA (OBDI) so the tach was no problem at all as well as the temp gauge.

The only thing is the speedo but wouldn't swapping to a DOHC speed sensor fix that problem? Because I was still running with my original KA24E transmission since the bell housing was the same. But I'm looking to get another transmission soon anyway.

1996-1998 Kouki gauge clusters need the S14 KA or SR manual speed sensor to read right. This is because the 1996-1998 Kouki RPS13 recieved an S14 transmission.

All S13 SR and KA-E and KA-DE speed sensors are the same part and dont read right in kouki gauge clusters.

im doing the cluster swap too...when you say mapped out the harness...do you mean signal, hibeam, lobeam, ebrake, oil pressure...ect. and then color code them?

i have the same cluster and was just wondering because two or three wire are the same color..what to do? i had wired it first color coded and then mapped it out but i think there was a few things wrong..like the ebrake light was on when the door open warning light was on..

any help would be great...

[Treyz]

I know that you have already probably wired it out and all but what I meant was mapping out from the back of the cluster. If you notice on the back, you'll see the copper flat lines that lead to the harness' female end. Right next to them they tell you what they are (i.e. GND, I.E., DOOR, etc.). I just simply followed those reading from the US to the JDM one. As for the E-brake light and all, I held it up to a light so that I can redirect the wires to the propper spot.

Now I still need a S14 speedo.
