thanks for the quick response guys. And sorry, yes it is 2001 s10 truck and s10 engine harness. I'm more referring to the pcm, ecu, fuse box and multiple little wiring boxes(see pics as reference) the firewall was cut( see first pic) and everything was stuffed under the dash and zip tied up there (super getto). I am wanting to get the wires and boxes hidden better match or slim down I'm 6inch firewall hole and wondering the course of action.
99 to life, i do like the idea of going through the cowl. I was wondering if anyone runs the wires through the passenger inner cowl and into the passenger kick panel compartment?(see last picture) and just hang as many of the wires as possible
