4. 240sx DOHC Cluster Harness or SOHC Cluster Harness


5. Tape or shrink tubing

6. Wire cutters

7. 10mm 12mm for temp and speed sensor





Wiring
S13 dohc harness and nx pig tails

any one who has done this pm me and i add info

[puerkone]

here is a picture of a s13 speed sensor

I have the set up too I just need help doing the wiring. I already mounter my nx cluster in my s13. =D it is awesome that you are finally going to help out do this conversion.

[nurvcom]

take some pics on how it mounted....

[puerkone]

I followed this link on how to mount it. All you do is cut the upper retaining plastic bracket and then the whole cluster slides in. Then you use 2 self tapping screws to mount the left and right holes of the cluster. Then, everything should fall in in place =D. now how did you do the wiring hehe I am in very need of your help.

if it works on the ka24de, that means it should work on an SR right?

[puerkone]

thats right as long as you have the nx temp sensor and speed sensor then you should be good. All there is left the wiring and nurvcom made this dream come true

[puerkone]

awesome I just saw the wiring diagram. I will install mines today and see how it looks like hehe. thanks nurvcom for all the great help.

[nurvcom]

yep if works on DOHC KA24de it work on SR20 and maybe rb20

[flip3d]

That's tight. I think I might buy an S13 just so I can do this lol

[reaper42240sx]

I know both the de and sr have been covered, and I know this is almost completely custom, but would it be able to adapt to the ka-e? That has to be one of the best looking clusters Ive seen. great job and great write up.

likewise lol Nice write up

[CrOW]

nice write up dude, big thanks to you guys!! but how about for s14?

if some get a cluster and harness and s14 cluster harness yes i would do one i did one for a guy for had s13 for 80

we could try anyone got a s13 sohc ka24e so i can test in Sacramento ca

[HellsDrifter 666]

I used a KA24E digital dash sub-harness to splice it into the NX one, it worked perfectly, so I don't see why not. I have a twin cam in my car, it used to be a single cam, but the speed sensor from a single cam tranny will make the speed read properly, and I did not have any problems using the twin cam temp sensor either.

[stinky_180]

Since this works with KA24DE and SR20, I assume the tachometer will not work with a KA24E. Am I right? Has anyone installed this on a KA24E?

Nice write up!

[HellsDrifter 666]

Your getting the tach signal from the dash wiring and the signal is not much different between the two so I assume it will work on both E and DE signal. My car was a E originally so all my wiring is single cam dash wiring. It should work.

[puerkone]

so now that I got the NX cluster hooked up in my car I am now going to try to wire up the HUD so it can work with the nx cluster. how to start. I saw that there are 3 wires that the hud uses. one gorund, one power and one signal from the mph gauge. I will try to hook it up this weekend and see if it worked.

If that was the case, then why doesn't SOHC tachs work with DOHC or SR motors? The interior harness is identical to both SOHC and DOHC. The signal however, is different. Do you think the signal is generated in the wiring? Something is sending the signal through the wires to the tach.. (duh). To my understanding, the signal comes from the CAS at the base of the distributor (i think).

The tach signal doesn't originate from the CAS. It comes from the collector of the power transistor for the coil. In the E the signal goes straight to the tach but on the DE the signal goes through the ECU for some signal processing. The simple solution is to get a DE tach and swap it in the gague cluster. You even have the correct redline then.
If you can't get a DE tach then you could try putting a scope on the tach signal coming from the ECU and see if it is 0-5V or 0-12V. I _think_ the E signal is 0-12V and the DE is 0-5V, but I could easily be wrong. If I'm not mistaken (ha ha) then you could build a buffer circuit to translate the levels from 0-5V to 0-12V and see if that works. If I'm wrong then it would probably fry your E tach, so be warned.

[stinky_180]

Maybe this will help make the NX1600 cluster work for SOHC KA24

Here's a little secret though. The KA24E has that same wire that goes through a resistor and to the ignitor. That signal is split between going to the ECU and going to the tach DIRECTLY. The direct signal and the sigal produced by the ECU in KA24DE's and SR's is different which is why the tachs arent directly compatable. HOWEVER, if you cut the wire going to the tach, and splice it into that signal coming from the ignitor, you can run a KA24E tach with your KA24DE. Both wires are yellow with a red stripe. I've had a single cam tach in my dohc for a while now works fine with that small modification.

[projekt_s13]

Tried this out using your write up and it didn't work. The two wire white plug green/white and red/black. The green is hooked up but where does the red/black one go? Also on the black nx plug it has two yellow/green wires and both are used so which goes where?

[HellsDrifter 666]

Depends on the year of the NX you got the cluster out of, you need to check on the back of the cluster where each pin goes because almost all of them are labeled on the printed board/flat wire on the back of the cluster. I think after 91 they are slightly different in the pin out.

[puerkone]

hehe it is so funny how many people did this upgrade. This is awesome.

Your retarded and should stop posting.

Not much? Signal from wiring? Assume?

You do not get your signal from wiring... try again.

[poo40vert]

You know where I could find the pigtail. I've had my gauges from my nx2000 from a while back but didn't get the wires.

Would any other pigtails work?

[onlydrinkkoolaid]

ok this maybe a truly dumb question but how would you get this to work since Im doing a 1jz swap

[98_240sx_se]

this is pretty cool. too bad its not for s14 though..

[RyanS13]

Did any one else get this done? PM me please.

My bad, I could have worded that a bit better, I meant to say distributor wiring. But I do think your being a bit too harsh. Would you like to give us some insight on how to make it work for a singe cam?

[poo40vert]

Has anyone done this with a 92 nx? If so pm me please
