which wire goes to FD tach to make it work??
 

Here is the question, I would like my tach to work in my FD, I have tried hooking it up to some wires, based off some wiring diagrams. But its not working right. I have a LT-12s w/ 3-rotor, and 6 bosch coils. Thanks for any info. So how do you make the sucker work?

check out www.ricemobile.net
If I remember right it's a white wire with blue stripe, but if you look on that website it tells you the stock wiring

blue wire with white stripes

I had it hooked up to a blue w/ white, but the tach and speed, jumped all over the place, not accurate at all. Is there only one of these wires going to the dash??

You'll find another. I did the same thing. Look on one of the other harnesses.

I am searching the connectors in the passenger foot well, is this where to find it at?

yes

Cant find another one, only see one. I may be retarded, but I looked at every single wire under there. And only the blue w/ yellow stripe does anything at all. Hmmmmm

I'll get off my lazy ass tomorrow and pull my stuff out and tell you.
