My ltcc system works great but i lost my rpm gauge signal when installed it and now need to know what wire to hook on my rpm gauge? The white from icm is connected to the ltcc system where it used to get rpm gauge signal.

If you haven't already done so remove the tach filter that 93's have.
Its a box with 2 white wires and a black wire going into it that is on
the wiring harness that goes over the driver side valve cover.
Stock it plugs in by the coil, splice the 2 white wires together, that should fix it.

i have done that allready, the problem is that my car dont have the icm anymore because the ltcc system does all the job. So theres no signal in the white wire. I´m thinking that can i take the signal from the 1 coil?

That won't work the tach will read 1/8th of what it should.
