Autometer speedometer, One input terminal? I understand by reading other post's that when hooking up an electronic Autometer speedometer that i need to "splice" into the wire comming off the tranny speed sensor but the sensor has two wires coming off of it and I only have one input on the speedometer, do i just splice into one wire? and if so, does it mater witch one? and what is the output terminal used for?
Thanks
Thanks

Verdad Gallardo How many people are using the autometer speedometer with an automatic? I had it on my car and ended uprunning into alot of problems, had to put a 2K ohm resister inline to the speedo. Trans wouldn't shift out of first sith out it. Just wondering if im the only one that had that problem.

I am hooking my autometer up to a 4L60E.

) If you just splice into the line like I mentioned I think your problem would be solved. I had a similar problem with mine in that it wouldn't let me shift into reverse, the solenoid for reverse lockout wasn't activating because of my bogus VSS signal. I bet your VSS signal to the PCM was also bogus. This would indicate to the PCM an incorrect speed and hence the tranny doesn't think it is time to shift. Just a guess as mine is a T56.Did you ever hook up a scanner to see the vehicle speed? Mine was always zero!
I am trying to install an autometer speedo now too. I want to get this right the first time so please let me know if I'm understanding this wrong. I need to connect a wire from the speedo and splice it into the VSS signal wire? In the wiring diagram I have it shows that the two wire coming out of the sensor are labled VSS high and low signals. Which one should I use? Thanks for any help you can give me.
If you're using a 99-02 LS1 pcm, hook C2, pin 50 to the signal connection of the speedometer. Ground the speedometer to the body and calibrate it per the Autometer instructions and it will work correctly.
This will absolutely not work with an Autometer Speedo. That 4k pulse per mile is a square wave and the Autometer will only work with the sine wave signal directly from the VSS. Also, do not cut the VSS signal wire and then wire the "Sig Out" from the Autometer to the PCM. This will screw up the PCM and cause a VSS error code. YOU MUST splice into the VSS and bring a wire to the Autometer and don't interput the PCM signal. I know because I wired it this way first and the Speedo did work but the vehicle speed was always zero mph causing other issues, mainly coming to a stop and nearly stalling.
The speedometer is designed to operate with an electrical speed
sender. The speed senders signal pulse range must be between
500 and 400,000 pulses/mile. Any speed sender or electronic
module that meets the following two conditions can be used:
• Pulse range generated proportional to the vehicle speed
• Output within the voltage ranges listed below:
2.0 to 16V peak (Square Wave), 3 wire
2.0 to 120V peak to peak (Sine Wave), 2 wiresender. The speed senders signal pulse range must be between
500 and 400,000 pulses/mile. Any speed sender or electronic
module that meets the following two conditions can be used:
• Pulse range generated proportional to the vehicle speed
• Output within the voltage ranges listed below:
2.0 to 16V peak (Square Wave), 3 wire
And if you look up Autometer's own 5291 & 5292 speedo senders, (http://www.autometer.com/download_instruction/0776A.pdf), you'll see that they are a 16 pulse per rev square wave.
No, he's right. Autometer speedos work fine with square wave. My Autometer UltraLite II works perfectly off the 4K PPM square wave coming from C220-K with a 99 Fbody PCM & harness. And by perfectly I mean that I've got over 1000 miles on it without a single problem, and I've verified my calibration against my GPS. In fact, if you read the AutoMeter instructions (http://www.autometer.com/download_instruction/1029A.pdf), you'll see this statement:

Rodder, I was going to use my C220 wire also......which spot did you hook it to? I have the Autometer instructions here, but they say to hook to the SIG terminal and then run a wire from the OUT terminal to the computer..>???
