I have tried many times to use any existing tunnel, but can't add any cable to them, they are so narrow and can fit only existing harness... Can't run there 10-12 wires, this what I need..
There are some more existing wire tunnels, but to access them is much complicated... engine covers it...
Steering column.. I imagine is so hardly to use, not?
I have idea on to pass cable trough AC air flow-in at top of car... maybe I'll try it some day, but Its need to do it carefuly to AC fan not touch wires...
P.S., Matt, i have figured out what below right-up and left-up plastic covers are some grommet 2-3 inch long and 0.5 inch round with marks "R" for right and "L" for left, for what is it, did you know? I have tried to run wires there - but nothing
Thanks to all for start answer here
