well, yes. I also like to do things the hard way.
The old jeep (2007), has the battery tucked away under lots of plastic, not easy to access. The new jeep actually has the battery inside under the passenger seat floor board. Go figure. There are remote jump start terminals under the hood though.
I like using the rubber welding cable 4 ga, it's more flexible in the cold than the plastic cables from the store. Better clamps too.
I build and attach a Plug/Pigtail to the jeep, then these cables can just be plugged into that. No worries on that end of getting things reversed or shorted out. Peace of mind knowing that one end isn't going anywhere when using it. I've got the same setup on three vehicles. custom length, I think this set was 17 feet. I solder all the connections so they don't come lose. (wiring nerd)
Total i think was $130. A bit cheaper than I see online.
