Code 24 after doing GNX dash mod

[696]

Look behind the radio to the left. You'll have to send the signal from the output wire on the VDO sending unit to a Casper VSS Converter. Then send the output of that to the brown wire on the green VSS box on your car. If you read the thread I posted the wiring lay out explains a lot.

Yes i did look over the info in the link you posted. Since the computer was getting a signal for a breif period im just trying to figure out if the car already has a converter as part of the poston kit. Otherwise looks like i need to order a caspers unit.

Bouncing speedo sounds like the signal is being interrupted. Check the entire source from the tranny and I'll bet something came loose, dead end sender, somewhere the signal wire got nicked and could be grounding out, ect.
What did you use to send the signal to the ECM (brown wire on stock green VSS box)?

PM sent. I tried to up load a file here but won't work so I will e-mail you the wire diagram that was sent to me with the dash...
