peter 20 Posted November 6, 2006 Just a quick question that i cant find the answer to using the search, I know that you need four diodes comming from each section of the coil pack to feed the rev counter however where do i connect them?,i asume that it would be the low tension side of the coil pack that is a 3pin plug with a smoothing capacitor (i think) so do i just connect 3 or maybe just 2 diodes to these and then to the rev counter? I hve studied the wiring diagram but can't quite figure it out. Cheers Share this post Link to post Share on other sites
pug_ham 244 3 Cars Posted November 7, 2006 There is another way TBH I can't see why there are four diodes, the rpm signal is fed from the ecu on the 2.0l turbo & GTi-6 are fed direct from the ecu so only one or two should be needed or suitably modifed rev counter as linked to above.

sonofsam 5 Posted November 7, 2006 Have also read somewhere that you use a Tacho head from a 205/309 TD and take a feed from the Gearbox speed sensor.How true this is I dont know? Share this post Link to post Share on other sites

sonofsam 5 Posted November 8, 2006 Yes Me too:)Seem to be doing OK without a rev counter at the moment. Share this post Link to post Share on other sites
pug_ham 244 3 Cars Posted November 8, 2006 I got a working one from an MP3.1 ZX that fitted straight into the 205 clocks with no extra work except moving one wire. Graham. Share this post Link to post Share on other sites
