install tacho, find 'pulse wire'?

[superspit]

hey friends,

It wasn't until I bought a turbo car that I would realise the potential importance of having a tacho (with a bright 'shift lite' (?)). I initially thought these devices were for the 5 second drag community or show-offs, until I found that every day I bump the engine cut-out at 7000 rpm (aprox(?)) because I cant see the standard, obscured by the steering wheel, tachometer.

I have not purchased one yet, as there are so many types and silly sizes to choose...plus I know very little diff between what a quality one should be like compared to a cheapy. ($100-$375). I have allowed myself $200 for a tach.

Is this ok? should i spend even more. All i really need is a big bright light to tell me when i'm 'bumpin the curve..'

[B]Plus..... where do i find the 'PULSE' wire or 'read' wire for the actual rpm sense on my car (pictured to left)[/b]

what can i splice into....ahhhh!

i can't wait to get a tach, and an answer here would put me at ease (no auto-elecs visits if i can avoid it!!!)

Thanks so much in advance....Mark.

You have to tap the 'tacho' output from the ECU. A wiring diagram should point you in the right direction. Do a search to find it!
