fitting aftermarket tacho

[mark]

hi, what im looking for is info on what tacho's people are using and where they have postioned them, tacho porn is what im after, so get your clocks out,.............. i said clocks......... also what make/brands are accurate.

also i was going to use angeloevs link for fitting https://club8090.co.uk/forum/viewtopic.php?f=39&t=70384" onclick="window.open(this.href);return false; but its no longer available. im fitting to a 1991 2.1 dj and from my research on here all the wire's are in the dash pod if anybody can tell me or point me to another fitting link that would be fantastic

thanks mark
