for referance and for easier referance:
1. battery ground to chasis= yellow
2. battery positive to alt positive= red
3. battery ground to engine ground= white
4. intake manifold to chasis ground= blue
now step by step:
1. battery ground to chasis
this is the easiest and quickest to do of the big three. took off the bolt and sanded it down, placed the wire back in and bolted it back on.
2. battery positive to alt positive
this one was a little more work. i found the best way to do it was to lift the car up on ramps. take off the black plastic cover right under neath the engine and work both above and under car. but it could probably be done with out unscrewing the bottom plastic cover.
3. battery ground to engine ground
pretty simple also. bolt and wire are pretty easy to spot. pretty much right next to alternator. also did it while i had the plastic cover right underneath engine cover taken off. this bolt is facing down towards the ground when your looking down on the engine standing up. so you'll have to get underneath the car and take the plastic covering off to get to it.
4. intake manifold to chasis ground
second to easiest connection to do. just have to make sure to route carefully, because the hoses around it get extremely hot and we dont want the 0 gauge to melt or cause a possible fire.
summary with all wires in view (color coded):
so this was the big three. hope it helps. tried to do it step by step and did some color codding. i know a bunch of wires that look like the rest of the other wires can b a little confusing to follow in the mess of an engine bay. hope it helps. il post a few more later of my finished product once my wires are connected witht he battery terminals and not just sitting there.
heres a before and after i had the zero gauge ran:
