scottmiller Posted October 20, 2009 Share Posted October 20, 2009 hey, i brought a tacho to install in my r34 gtt today, i have spent hours looking through diy forums but i cant find one that tells me which cable is the revs. i dont reallly want to run a cable from the ecu i just wanted to tap into the old one. any info would be great cheers Link to comment https://www.sau.com.au/forums/topic/292694-r34-tacho-install/ Share on other sites More sharing options...
RusH_ Posted October 20, 2009 Share Posted October 20, 2009 sorry i cant be much help, but im just curious as to why you would want to install a tacho when you already have one next to your speedo? I've never really understood why anyone does this on any car to be honest?

blind_elk Posted October 20, 2009 Share Posted October 20, 2009 You should find that the current tacho runs on a signal from the ECU. Just find that wire, and you should be ok.
