battery relocation, some help Options

[Malhar95]

my engine bay doesnt really have enough space for some reason even though i have a stock(ish) 5s. so im looking to relocate my battery to the trunk.


two things...the previous owner(s) really kept effin the terminals so the wire which connects to my positive terminal, is really short so thats causing my battery be closer to the engine and hence taking more space. so either i relocate my battery or just extend those wires.


so the question is:
1. how to relocate a battery for a noob?
2. how to extend those wires without buying a new harness?



i would obviously choose the easier/cheaper option so please help.
thank you in advance

just buy a smaller battery and leave it in the front?


IDK. Toyota relocated my battery for me

but what about that bs autozone and other parts store give u when i ask them for a different size battery...i asked them last time when i was getting a battery, they said if "i get a smaller sized battery, its gonna mess up the cars electrical system and life" even though i was just askin for the same 12v just shorter height battery.

there is a small wire u can just crimp another small gauge wire to it to extend the wire, and a bigger maybe 4ga wire you can just replace with an autozone switch to starter wire, or u can get the type that is a positive terminal with the 4ga wire already in it.

relocating it would take a lot of 2 gauge wire running from your positive terminal to your starter and then the smaller wire to your starter too... then just ground the battery to a good chassis point wherever u put it.

(if relocating)
hmm so in short just connect the positive wires to the starter and ground the battery?
sorry didnt quite understand that concept?

(extending the wires)

lets say i got the terminal with the wire in it, when im connecting the new and old wires, should i solder them or just twist them together and just tape/cover it up?
