Autometer Speedo hook up
Autometer Speedo hook up Its all hooked up and im having problems getting it to work. I called autometer and got the wire to the VSS hooked up at the tranny. All the other wires are right, and went through the programming where you drive the car 2 miles... Still no luck. Anyone else hook this type gauge up. Its in my Ls1/M6 Chevy Truck.
Any help would be appreciated.

I don't really know much, but will have to do this soon. Is this a newer autometer speedo, if so the can take square wave and sine wave inputs. One is from the VSS sensor and the other from the PCM output. You should probably be able to hook up to the Speed output on the computer.
Someone else will probably chime in that knows more, but that's a start. What year is the LS1?

I have a programmable Auto Meter hooked to the PCM output with no issues at all. Does the speedo do anything in programming mode? Mine displayed the pulses as I drove during the programming. All I had to do was hold the button while starting the car, drive to the beginning of the mark hit the button, drive 2 miles hit the button again. No problems at all. Are you getting a good VSS signal to the PCM?

I looked in the sticky. It links to here: http://www.ls2.com/boggs/torques/98pinpcm.htm
Looks like pin 35 Blue, but not sure.

If you still have the wire in connector 220 pin G that is where the speedo signal comes out of the factory harness to go to the speedo.
If not you can hit that wire as it comes out of the PCM, it is #55 red connector.
stealth71: pin 35 blue is for the tach output.

Would the 220 pin G come out of the computer from the fireHawk computer?
This wire would be ran to "Sig" on the Speedo? And does anything connect to "Out"
Thanks a lot for your help.

Connector 220 would be on the wiring harness, it used to connect to the firebird dashboard. Depending on who did your wiring harness they may have left this connector intact, or removed it and any other unused wires. If you can`t figure out which connector it is trace the wire from the red connector pin 55 on the PCM.
Connect that wire to the signal in on the speedo. You should not have to connect anything to the output on the speedo.

Ok, on the computer there are two connectors. 1-80 the numbers are all wired.
There is no way to differentiate between the upper and lower. One is not blue and the other isnt red like the link states above.

The VSS output from the computer is a dark green with white stripe wire.
If your harness is a 98 there should be wires in both pin 55`s, one should have a green/wht stripe and is the speedo output, the other should have a LT BLU/BLK wire that is the output for the idle air control.

Ohh, and the upper connerctor is missing wires on pin 55. ? Im not sure why.
