C34 Speed Sensor

Hi guys,

I'm trying to determine what the wires off my speed sensor are. I've got a Black wire with a White stripe, and a Grey wire with a Red stripe. They both go through to the back of the speedo cluster and I'm really trying to figure out which one to tap into to get my speedo corrector working.

Also, is there anywhere to get a wiring diagram for a S1 C34 Stagea?

Cheers,

- Lance

If you have just two wires to worry about just cut one and hook it up and if that doesn't work cut the other. Can you take a pic of the back of the cluster and post it up or PM it to me?

I have a copy of the service manual but its in Japanese. I have copies of 5 pages relating to the speedo and if you PM me your address I'll post them to you (I am too tired to scan them just now).

I fitted one of those correctors to me c34 as well (inaccurate speedos bug me), I just did it behind the dash...sorry, I didn't take pics.

But on the rear of the dash it does mark which track is the speed in, which you can trace to the plug and then intercept the wire in the loom.

I've tried the process of elimination Bob, but neither seem to bring any joy.... Which seems weird. I think I'm having issues with the actual module now (even though I purchased a second one just to make sure it wasn't that)

Duncan, the plan is to mount it behind the cluster and splice it into the loom there. I don't suppose you remember if there was anything funny about setting it up initially?

well actually I do remember something funny, but didn't mention because I think it was a red herring. And it was about 10 years ago. Basically I remember I reset it multiple times and it didn't flash the way it was meant to. But because I don't remember anything about the details, and I never knew what the issue is I don't think that helps :blink:

Lance it seems to me that interrupting the circuit at the screw on the back of the speedo is still the best way. I am sure you have worked out how the spacer and tabbed washer will achieve that and you just have to work out which screw. If you look on the pic of the GTR cluster (which is quite different - especially without all the auto lights) you can see some Japanese characters next to the speedo signal and I wonder if you can see those same characters on your cluster (the photo is not clear enough for me to read).

Good to know that it's not just me having a problem setting it up, Duncan. I've emailed Jaycar in the hope that someone will know what's happening and steer me in the right direction.

I've pored over the back of that speedo, Bob, and I cannot find those same characters on the back of my speedo. I've even painstakingly traced the track from the pin, all the way through and no where does it have a screw intercepting it.

Cheers,

      Big Brake Kit for ECR33

      By Dose Pipe Sutututu · Posted

      Really comes down to user requirements, I have found my 324mm 350Z Brembo front set up more than sufficient for track use, especially for Wakefield Park with good brake pads. At Sydney Motorsport Park the GP Circuit can be a bit taxing on the braking system, I find by the 3rd hot lap there's rapid degradation in braking performance but at that point non semi slick tyres are about to give up anyway. And yes, the brakes are effective, slowing me down from 230km/h+ each time going into turn 1. Street use, it's more than enough for street activities. Most of the time people complain their brakes aren't sufficient, it's due to incorrect bleeding, poor choice of friction material, or faulty master cylinders.

      I'm about to sell my Attakd kit actually, so if you want a budget 2nd hand kit they definitely do work, though make sure you update your BMC when/if you do. Just keep in mind that buying pads (for any aftermarket kit) can be a bit more complicated when you have an aftermarket caliper. Not all brands make pads in the shapes and sizes you may want, no matter what you end up with.

      Wiring loom difference between A31 A/T RB20DET and R32 M/T RB20DET?

      By deuceforty2 · Posted

      Hey guys, I had an R32 M/T RB20DET in my S13 quite a while ago, however I have replaced the chassis harness on the S13 and picked up a new motor (A31 A/T RB20DET according to the ECU) and I am having a hell of a time trying to figure out the dash wiring (specifically the black/pink wire for the fuel pump).  It seems this A31 loom is quite different at the dash connector and there is not even a black/pink wire anywhere on the engine loom (on one of the 5 dash plugs that are there), or on the ECU for that matter.  Every pinout I have seen is totally different from the actual wires on my ECU and i'm at a loss on how to wire this thing into my S13....     Any ideas?   In summary : A31 A/T engine loom/ecu pinouts are different than any pinouts i have seen online (specifically around pin 18 Fuel Pump Relay)

      What are you doing with the car? Drags, sprints, racing? A decent upgrade of dba 4000 rotors, good quality pads (endless, project mu, intima are all I have used), quality fluid and braided lines. All have held up to multiple big track days and street duties. No need for big fancy kits as some also require significant energy to come upto operating temp. Look at 350z caliper and rotor upgrade too.  @Dose Pipe Sutututu comment on them and did a good write up.

      I've driven that one and it's a great deal and drives nice. The owner definitely treats it right on track. You would have gotten it for what you paid for this one too.   Keen to see what you do to this one.
