Hello,

This is my first instrument who will be modified and I hope not the last.
I would like to use one tachometer. I put some pics to show which sort of indicator it is.

Could you help me and confirm which technology it is, can I used the drawing of this post to wire it ?

Thanks for your help... and sorry for my poor english!
