Running New harness thru obs firewall?

[1BadCC]

I wont need ABS, A/C, or my factory speedo. Will my power windows and headlights still work?

All of my wiring runs through this grommet behind the intake..PCM and relay boxes are mounted under the dash..

That looks so clean! I just may switch to that. What about the wires from the c100? Did u route them back into the cab also, where?

I got rid of the c100 plug and any wire that wasnt used. The tail light harness comes out under the drivers side floor board. The only wires that come from the driverside forward are the headlight stuff.
