what color wire and where do I tap into to get this R1 tach to work. I know that theres a power, ground, ignition switch and ignition coil. But what color is it on the prelude? And where is it under the dash or under the hood?

 

the tach wire is the larger blue wire on the ditstributor.........

umm....what happened to the stock tach?

 

I sold it to my ricer brother in law . And I'm buying a defi boost gauge with the money . Are you sure it's the blue wire cause I did a search and on some cars it's the yellow. How bout the lamp wire? Where's that at? Sorry for the stupid questions just a little confused when it comes to electrical wiring.
