I just created a decent write-up on silviav8forums.com. With whats been described in this thread i could not get my settings high enough it was showing 50mph when i was going 60mph. The biggest difference is I'm splicing into the red connector on your PCM pin #21 purple/white wire going into the input. I use output 3 to the s14 240 cluster wire yellow/red. Dip switches set off,off, on,on. Coarse adjustment 11 and fine adjustment 4 or 5 should be close using a j30 3.92 diff. I dialed mine in using a free speedometer app on my IPhone. For further detail check out my write-up here: http://silviav8forums.com/forum/viewtopic.php?t=5008
Power- 12v ignition keyed source
Ground- just ground it close to the box
Input- purple/white vss wire (this still needs to feed into your PCM so splice into it)
Output 3- out to your speedo s14 is yellow/red into the back of the cluster. S13 should be yellow/blue.

Anyone have any input on how to get this to work in my 98 240sx. I have pin 50 on my ecu to the signal input on my dd sgi 5-e. I have wiring specialties harness and i just cant get this damn speedo to work.
