Adding alternate battery posts

There’s a disturbing trend where auto-makers are placing the battery lower in the engine bay, and covered by plastic cowls. How in the world are you going to jump a battery in the dark, in the cold, when you have to remove 3/4 of the beautification plastic?? Any car builder, car mod guys out there that use a dependable product to allow you to add a second set of + and - posts where you could put a jump starter on in an emergency? Thanks in advance.

Yes there are commercial sold kits to extend the cabling to an auxiliary power block.

Used to add a bumper winch to a 4x4, or to add a secondary battery if you add a stereo that pulls lots of power, or to extend an RV system to add 12V appliances into the living area.

Look for auxiliary power block, and cables in an RV place.

I bought my son a set of cables and the connectors like Neal posted. Some tractors and lawn vehicles have batteries that are hard to access so with a little planning he can have cables and adapters to handle all occasions.

Honda Pilot. And before we turn on to “First Mistake Street”, my wife has to haul our two boys and a lab around, so there’s that.
The positive post is accessible, but the negative is buried under the cowl for the air filter. Yes, you could connect the negative to a bolt, bare metal surface, etc but I’m looking for a reasonably priced solution that would allow to her to execute under pressure.
She’s a tap-rack-bang kind of woman, refuses to be a damsel in distress.

08-15 pilot or 16+?

Like Huesmann said, ground is ground. The starter grounds through the engine/transmission anyway.

I'm a Honda Master Tech, so my opinion might worth slightly more to you. I can try and grab a pic of the easiest place that will work for you without needing to come up with anything creative once I know what gen Pilot we are discussing. Though it might take me 1-2 weeks as I don't go back to work until next thursday and I'll have to get the same style pilot to work on to get you an accurate pic.

Hi, Lawrence. Thank you for posting. The Pilot is a 16 + platform. I am not arguing textbook battery jumping. I understand ground and why the procedure has been steadfast for so long.In my family’s case, it is an accessibility issue. My wife is simply not that tall. There isn’t much in the bay she can easily reach. We both like the BMS in the Honda, but believe in having a back up. Any advice is much appreciated.

Just an update, I have somehow only managed to work on 1 pilot in the past 2 weeks and unfortunately I was working on 3 cars at once so I didn't have a good chance to investigate and snap a pic.

Going off of memory only, you might be able to just use the airbox bolt as ground if the cable reaches, I know we've used them as ground when using a miditronics battery tester doing it on lazy mode. Not 100% if I've ever tried to jump start one there. And yes while it's just a 6mm bolt(10mm hex head), the main ground bolt for the negative cable is also a m6 bolt.

I haven't forgotten though, so as soon as I can I'll try to get the best answer I can come up with.
