Trunk mounted battery cables

[Tom.A]

In the past when I used a trunk mounted battery I ran the cable along the frame however I have seen some guys using bulkheads and going through the interior of the car. Looking for opinions and or any concerns through the interior.

Thanks,

I don't see a problem running it through the car. I'd recommend looking into a mega-fuse located the battery like American Autowire offers.

Tom....I ran mine through the car as well. Worked out perfect. Let me know if you need some photos.

Through the car with a firewall bulkhead here too. The only downside is that 00 cables are bulky and don't like to turn and you've got two of them. Hiding them under carpeting can be difficult without a lump showing.

Can't tell mine exist where I routed mine.



Then I installed 3/8 jute on top of my sound deadener and cut it around the cable so they were recessed. If you want you could even tape over them with aluminized tape like I sealed my joints with on the jute. Didn't think it was necessary. Then I used a bulkhead for the positive on the flat shelf above the kick board. Grommet for the negative.

Well, you'll have to look pretty hard to find mine... but it wasn't easy.

I routed my cables almost exactly the same way.

Why are you guys running your ground all the way up to the engine bay?

Why not just ground to the rear frame?

[parsonsj]

I ran separate ground cables for all devices... I'm not using the car body as a ground.

Thanks for feedback and pictures I will follow your guy's same route and go inside the interior.

Your main ground should be on the engine. I then have a ground strap to the body from the engine. I'm sure it would work grounded to the frame but from my research running the cable to the engine is superior.
