jessejames Posted December 13, 2007 Share Posted December 13, 2007 My engine is in, most of the wiring is done. How do I hook up an autometer mechanical speedometer to this motor. I think i'm going with the 3.90 rear end, and will end up with 16 inch rims at some point. Somebody mentioned to me that the white speedocable connector will work, is this true?

mr jdm Posted December 13, 2007 Share Posted December 13, 2007 how you going to get this to work, sr20 trans is electrical not mechanical, you need the electrical autometer gauge i would think. Quote Link to comment Share on other sites More sharing options...
SR240Z Posted December 14, 2007 Share Posted December 14, 2007 you can put the mechanical speedo cog from a ZX trans and it will work with the original speedo cable. Electrical speedos are much more accurate though because it runs off pulses not just off the cog you have in the transmission. Quote Link to comment Share on other sites More sharing options...
