I went back and forth for a while between the dakota and original gauges, really like the look of the originals so I pulled the trigger and brought a new set. Then I find to get the speedo to work I will have to spend another $3 to 4 hundred dollars (convert the signal. So now my next question is how do i get the oil pressure to work? I know the old style had a tube running the oil pressure to the gauge, so where do I run the tube from on an ls-1 engine? love the look of the gauges and will keep them just did not do my homework before hand. Also I'm not an engine guru so this may be a simple fix i don't know ??
