First off, big thanks to SinisterSentra91 for taking the time to do a wiring diagram for me. It would have taken me way too long to try and figure it out on my own.
Here's a list of items you need to get the job done. (This is if you want to use my method, there are other ways to do it also).
- Wiring diagram
- Digital Cluster from 91-93 NX1600 (with harness!!)
- Crimper tool
- Interlocking connectors (I used a 15 pin and a 12 pin)
This is the wiring diagram provided by sinistersentra91

here for a bigger picture.
Here is the crimper you need, connectors, and plug. (that's a 6 pin connector, which I did not use, only used for picture purposes

)
Best way to do this is take a wire one at a time from the digi cluster, put the pin on there, stick it in the connector, and do the same to the other side once you find the wire coming out of your harness.
I decided not to cut the stock plugs in case I ever wanted to swich back, I just tuck new harness behind the dash, and use the analog one. I just stripped each wire, and wrapped the wire from the new harness on. I'll go back and redo this next time I pull the dash out.
Its pretty time consuming finding each wire on the harness, stripping it, putting the pin, matching it up, etc. but do that one by one for each side of the harness. Depending on what factory options your car and the digi cluster car had, there will be some wires missing. IE, my cluster didn't have a cruise wire, and O/D wire, so there will be close to 30 wires total.
When you're done, you're going to have a lot of wires coming out of each plug.
Use some electrical tape to make things a little neater.
When its all said and done, there will be a lot of wires, don't let this next pic scare you, its not for the faint of heart
I failed to get a pic of the back of the digi cluster after the harness was made, but I'll get that up soon, since I need to pull my cluster out again in a few days.
Here's what it looks like when done.
The speedo does work, however after 30mph, its a bit off. And at around 55 on the anlog cluster, the digi one shows 60. So the faster you go, the more off it is. Hopefully the NX1600 speedo sensor will correct this problem.
I tested this by using both clusters, analog one in the dash, digi one in my lap
The tach on mine does not work, but the wiring diagram is correct, I tested another cluster, and that one worked just fine. So I need to find myself another one.
As soon as sinistersentra91 sends me the link, I'll post up the wiring diagram. He's still working on a solution for the dimmer at the moment.
And here's a random pic of the cluster I took at night.
Well, that's pretty much it in a nutshell. If you guys have any questions, ask away while its still fresh in my mind.
