ok i have a 93 sx with rb20 red top. I need to relocate my battery to the trunk, I have 0 gauge wire can i just hook the factory terminals to the new wires and run the wires to the trunk to the battery? Or do i need a circuit breaker or something?

Any help would be great even better if someone knows a cheap way to do it i have about $9000 in motor and mods so the wife is starting to nit pick.

so i guess in short can i just hook new wires to factory terminal and run with it?

i have so much under the hood i would like to put it in the trunk. Also i have elec boost controler turbo timer boost, oil and timp gauges and a afac ll pulling power not a lot but it pulls some. My lights will flicker and dim, I have a small honda battery in her now.Do you know if i will run into problems if i just conect the 0 gauge wire to the factory power wire and other wires on the pos. side, hook the neg wire to the frame and run the o gauge to the trunk to the new battery and a short groung somewhere in the trunk?

the 0 gauge wire from the terminals.......that would be fine....someone else chime in about the circuit breaker, it sounds like an idea but im not totally sure if its necessary

If the cable is shielded properly you shouldn't need a circuit breaker,but i don't think it is a bad idea either .

So on my setup I used 0 gauge from the two wires that are attached to the positive to the main cable to the starter. Then starter wire from starter to the battery in the trunk. Small ground from battery to the chassis in the trunk.

Yeah, you can hook up a +cable running from your battery from the trunk up to the factory +connection up front. As for ground, you will have to run a cable all the way from the battery up front to the engine bay. Just hook that new ground up to the intake manifold where the factory ground is located.

I have mine this way, I skipped on running a ground from the battery to the front and had problems. My connections on my alternator got extremely hot, and even burned off a couple of times. Since then I've run a ground from the battery to the front and replaced my alternator wires and haven't had an issue.

I figured the ground would travel the entire length of the car regardless of location, but apparently it's not that simple heh..

btw the cheapest way to do it is to just go to autozone and get a set of the 16ft jumper cables, they're perfect
