I have a Y1 cable tranny that uses a mechanical spedometer. I'm hooking up an Apexi avc-r boost controller and i need to connect it to and electronic speed sensor for the gear function. I can get the sensor from the junk yard but how do i hook it up. any one has wire diagram. i will be monitoring speed with the avc-r.

 

I think it just needs +5v, ground, and signal out. You can probably tap input power and ground from the MAP or TPS sensor, and just run the signal wire on the VSS to the avc-r.

However.. how is your speedometer gonna work now?

so the power source for the map and tps is 5v? seems easy enough. i'll try it out,
thanks,

Yes, MAP and TPS both have +5v in. But unles you go to a cluster w/ electronic speedo you won't know how fast you are going hehe

 

the avc-r has speed read outs, which is good because my OEM speedo only goes up to 120mph, so i'm set.

 

you dont need to buy a speed sensor. The speed sensor on the crx is at the gauges. Connect it there to get the speed sensor signal.

 

so, there's probably a wire from the speed sensor to the ecu. do you know which wire.

 

from http://www.hasport.com the VSS wire is pin b16
You could also get the signal out of the back of the gauge cluster

sweet, thanks racexadam! what does VSS stand for any ways.
