Hello I have a celica year 96 T20 1,8 16v and have a 4" tachometer to install but not where to remove the cable from signal. Where I can join the wire? you can put some photo? I am of Spain and I have problems with ingles to try that the description is basic, thanks and greetings.

I believe, after reading through the factory manual and getting what I could from it, that you have to tie into a grey wire that is coming out of the back of the tachometer. I am not completely sure but this wire is tied into the ignitor's wiring and also into the tachometer, so I hope this is it. If that doesn't work you could use a wire tap and try all of the wires coming out of the back of the tachometer, but I am not sure you would want to do this.

Welcome, and good luck.
