OK, need some help here... Trying to wire a car

[ROFL BOX]

Alright... Im all kinds of puzzled here.

Im currently working on an 04 5 Door Avewoo, Doing the "Big 3" and running a power supply wire into the cabin for amps. Now with my personal vehicles Ive had no problems because I can easily access the grommet in the fire wall where the factory harness runs inside the car... The only problem Im having is of course with the smallest engine bay that I have touched, thus spawning my impromptu registration to yalls little slice of the internet (very nice place if I do say so)

Right behind the battery, as most of you know, blocking access to the fire wall, is the fuse box and the coolant overflow tank.

Thus bringing me to a standstill with the vehicle.

Do I run the main power wire from the inside out and hope I can grab it from up top?
Do I remove the overflow tank (3 hoses and 4 bolts) to get to the firewall?
Do I just run the main wire through the fender well and into the floor pan?
Or is there an easier option that Im really overlooking?

Thanks in advance for the advice

theres a hole in the firewall right behind the gas pedal... big enough to fit a 0ga wire thru with very litle squeeking room..

You missed the question here... While in the engine bay, how do I get my large arms to the firewall without taking the coolant reservoir off? I know where the grommet is, I just cant imagine how to get to it...

Become a contortionist. XD
lol. In all serious-ness, I'd just remove anything in your way. This is the mentality I HAVE to follow when working on my Monte Carlo (See picture below). But the people here who actually own an Aveo might provide better insight.

Went today and picked up the wood for the box

the main harness goes out to the fender on the drivers side foot well, runs up the fender, and come out at that fuse block. thats the rout i would take, removing the head light and fender signal to ease routing. it will also keep the wiring out of the engine bay for a cleaner install.

but otherwise, you can unbolt somethings, but you kind of just learn to work with tight spaces.

the way i ran my fog lights through the firewall was i took a stiff wire and my dad. i pushed the wire through firewall into the engine bay and kept going until i could reach it. it took a couple times and some bending but it worked very well.
