Hey everone i have a 89 civic and i wanna remove my cluster to make room for gauges and its a t/s and sfwd car. My question is how will the vtec, 2 step, or anti lag work without some way to know the speed. I talked to a couple people. one said wire a electronic vss straight to the ecu. another said i could use the abs sensor on a rear disc setup and wire that in. whats my best option and will either work. thanks

 

Dismantle you gauge cluster and pull the speedometer out of it. Zip tie it to somewhere under the dash and plug in the cable from the trans to it. There are two electrical posts coming out just under the cable plug. One is a vss signal, one is a ground. Trace the traces on the back of the cluster to see which is which

Left is ground, right is vss now that I think about it. Ground to a piece of metal under the dash and run the vss post to the wire thats already in the dash

 

I would just put a electronic speed sensor in it.

 

so ur saying just wire the electric vss strait to the ecu and no cluster right. if so does anyone have the pinouts for the electric vss and ecu for theose wires. lmk thanks

 

Electric VSS wired to ecu. Its how I ran my CRX hotrod

 

thanks i just wanna get rid of the stock cluster and still have the essentials to go fast work.


Garage 808. do you by any chance do u have a pinout diagram to wire it up. thanks

 

Damn, all the wiring direction you need and the noob still gets shunned

 

LOL. Im with Paul. ****, I was gonna consider just putting my cluster somewhere tucked behind the dash, and put a Tunerview RD1 in the cluster's place. But I like the idea of just having to hide the speedometer back there, and rewire the two pins.

Good call Paul. When it comes time, youll have to help me with that.

 

Gotcha Curtis, give em the direction they need and they still **** up a stiff rope.

 

JFYI: i hate to tell ya that im not a noob and thats why i wasnt listening to ur idea of rigging the speedo behind the dash. all it would take is one hard shift or a nice bump in the road on my 18ft car trailer and that falls or looses its ground and ull loose the round or get to the track and the cars not running right. Plus im not doing everthing else on my car to make it nicer and presentable for potential sponsers and yeah have under my dash rigged like a ticking time bomb waiting for me to loose a round of racing that will make or break a potential sponser or possably blow my motor.

 

are you running OBD-1 with a b-series? that what i have in my crx and i can check the pin outs on my ecu.

 

electronic VSS is the way to go. Pinouts can be found rather easy. I can email if you just absolutely cant find it.

Pinouts

 

Way to jump on the defense. JFYI: check the post count. I WAS referring to myself as the noob, but since veteran members cant put 2and 2 together I guess we'll get back to putting you in the noob spotlight. JAFYI: ive had mine zip tied under my dash for 3 plus years, 400 plus 10 second passes. Hadn't blown up a motor or lost a round yet due to the cable popping loose. Btw both ends of the cable have clips what good excuse would you have for it poppin out then.

 

I was gonna say. The cable has a clip. Thats why it doesnt "pop loose from hitting bumps" in the road as a factory setup.

And if youre looking to make your car nicer, and have sponsors, and blah blah blah, why are you putting a million analog gauges in your dash, and having to eliminate the gauge cluster anyways? You could always get a Tunerview or similar, and not need one of those gauges.

 

the H-T thugs are here...

Anyway, electronic vss is ideal...

 

The electronic VSS only has 3 wires, power, ground, and signal back to the ECU. It is rather simple to connect.

 

Whos being a thug?

 

If you run the neptune rd1 doesn't it pickup vss. From the usb interface that's hooked to s300?

 

thanks for the help guys. i got what i was looking for.
