    Running wires through the firewall?

    Does anyone have any tips on running a few wires from under the hood (fuse box) into the cabin? Where did you run them?

    (Installing ZR4 laser shifters, so if you have any specific installation tips, I would appreciate that)

    -thanks.

    I cut a small hole in the rubber boot at the firewall where the steering column goes through. I then use a metal coat hanger to push through. It may take you some time as it is thick. Make sure where you are pushing there is nothing on the other side.
    Hope this helps

    ^^^^this^^^. Probably your best bet is to fish a hook through the rubber boot. Make sure those wires in the engine bay are protected from the heat. Then it's just a matter of making sure the lasers are well mounted, 100% level and IMO as close to your headlights as possible.

    The leather punch on a pocket knife works well too.
