How to pass-through a wire from dash to engine-room

[myth]

I am installing a remote-starter. Starter model is Ultra Start G11t and installed on the Legacy L Sedan Auto 2002. It cannot work without tach-signal, unfortunately. So I connected the tach-wire to the ignition coil in the engine-room through the window. Then the remote-starter works perfect.

Now I need to pass-through a wire from driver side under-dash to engine room. I checked the under-dash but cannot find any hole to do it. How can I do it?

drill a small hole

 

or, there is a rubber grommit that 3 or so hard lines go thru (i think they are fuel lines)

Removing the TMIC will give you access to a giant grommet. See pictures here http://www.legacygt.com/forums/showpost.php?p=2101962&postcount=130

 

 

eta: nevermind I see it's a 2002 your working on. Probably not the same.

or just get the tach signal from the gauge cluster

My friend and I installed one it has baja, we got the tach signal from the gauge cluster and it worked fine.

I used a rubber grommet. Put a wire through it and plug the grommet again. But it does not fit again.

Thanks.
