If you ask the install bay at your local car audio shop for some, they'll probably give them to you for free. They cost them less than a penny each.

Thanks for the writeup it worked great. However I did locate the blue/white stripe but didnt get any voltage from it and I found another blue/black stripe coming out of the ECU also with no voltage before I found teh other blue/black stripe that worked. But it works now and no drillin or clunky wires in my sweet engine bay.

Im having an issue with the tach droping to 0 when I let off the gas quickly, anyone got an idea what it could be?

Bump for a dead thread... I have 2 issues here. I am swapping a 91-92 NX2000 gauge cluster into my auto-manual swapped 94.5 XE. I have pinned out all the wires needed, put a speedo pinion into the tranny, cut a hole and ran a speedo cable to the cluster.

For the tach, I had an aftermarket one I was only able to get working by hacking the coil and running a wire to (the blue/black wire at ECU pin #2 didnt do anything). I tried running that same coil wire to the new cluster for the tach signal, but that shorted the ignition somehow and the car would only crank and not start. Disconnecting that wire, everything works fine.

EXCEPT no speed info. I somehow thought that with a cable-driven one I could ignore the cluster wires for the 'speed sensor' - the XE had 4 wires and the nx one has only 2.

Do I need to power the cable-driven speedo for it to work? If so, what wires could I choose (on the diagram it looks like the XE had 2 powered and 2 ground wires)?

For the tach, has anybody else been able to find an alternate ECU harness wire that carries a tach signal? I ran ECUtalk with a consult cable and got good RPM data, so I know the ECU is getting a signal from the engine.\

Thanks for any help/ideas.

Bump c'mon I don't want to start trying RANDOM wires in the harness looking for a tach signal...anybody have a different signal wire??

Dan9 · Aug 13th, 2007, 03:17 PM

Ok So I put the ECU tach signal wire to the correct position. Speedo cable is installed right, and all should be well.

But, no tach and no speedo.

I am wondering if it is possible that I fried tach and/or speedo when I used my coil hacked wire for the tach signal, and the car only cranked with no start.???

Any way to test the tach and/or speedo? The cable is good. The pinion is good and all the way in. I have wired up tach and speedo as per toolapcfan's writeup.

Only other things I can think of are, I didnt wire up the water temp sensor, since mine doesnt give a good signal anyways (I have aftermarket so it didnt matter to me), I also skipped wiring up the buzzer, seatbelt light, washer indicator and similar useless crap.

No motion at all from speedo or tach at ACC or when car is running, and moving.

Weird. Looks like I downgraded since I already removed my mini-tach.

I need help now my car won't start, Just keeps turning over and won't start did I hook a wire up wrong? Help please

hey i want to install a tach for my Sentra 98 GXE, can you guys tell me the color wire out of the ecu that i need to use?

Dan9 · May 21st, 2008, 11:26 PM

I want to connect an SE-R cluster up to my XE. In fact, last summer I tried to, but some speedo issues made it worthless(for teh time being) and I put back my XE cluster.

The problem I had was in getting a stock tach signal from teh ECu harness so I could get the stock SE-R tach to work...I tried using the coil wire that I (had to) hack for my sunpro tach, but that just caused a short and teh car wouldnt start.

I cant figure out why the stock wire wont give me tach signal.

joenathan89 · May 24th, 2008, 04:19 PM

you sure you used the right stock cable from your distributer? One is a positive cable and one negative. you want the negative. Try testing each one with a voltometer while you rev the engine. if the volts jump when you rev it, thats your tach signal

make sure you have a really tight connection between your tach wire and the signal wire. Use soder, or wrap it really tight.
