I figured I would get more responses in here. I just installed a Greddy Auto Turbo Timer and cannot find a VSS signal due to the fact that my A33B does not have a VSS (manual). Greddy is telling me I am pretty much SOL with that feature of the device. The turbo timer still works if I set a time for it to run after ignition is turned off, but I would like the Auto function to be enabled (hence the fact that I purchased this particular model) and it won't with a speed signal.

Is there another SAFE place to get the VSS signal?

 

cant you pick up the signal from the ecu to the cluster?

 

No VSS wire at PCM. It is probably a bynary signal.

 

VSS from Quest may work. I will buy one and wire it in. Will see what happens.

 

The 4th gen vss sensor will fit in if thats what you need. I know. Im using the 4th gen vss in my 6sp.

 

What year 4th gen is it and auto or manual?

 

same sensor for both but mine came out of a 97 auto.

 

vss wire is behind the cluster behind the speedometer. I forgot the color but if you search in the audio forum they will have the answer there because a lot of Navigation units need the VSS wire. Good luck

 

Wire 68 on the ECU plug is the speed signal.

at 6mph its 2.5 v

at 19 mph its 2.0 v


page EC-148



im a 6spd too and i have this wire, its to tell the ECU how fast the car is going for cruise functions and i think speed limiter.

 

pretty sure its a pink wire behind the cluster.

 

Wire 68 on the ECU is VSS, which is in fact the pink wire behind the cluster.

Thanks everyone for your help!!
