How do you install this and still put the positive battery cable on the battery?

The FACTORY cables connections will have to be cut and made to work with this new terminal. Just like you would do the aftermarket power wire.
[ Brian  Jun 09, 2017 ]
If you have a top post battery this is the way i did it. if your wires connector screwing into the side of the battery like a lot of Chevrolet's do. Then DON'T use this info. Pull the wires out of the factory battery clamp. Then run them into the new battery Terminal. If you have to cut the factory clamp off, just strip the wires back and put the bare wire into the terminal.
[ Douglas  Jun 09, 2017 ]
You simply remove the existing terminal from your vehicle's positive wire(s) (You may have more than one positive wire supplying the vehicle). Strip approximately 1/2" off the end of your wires so they are bare/exposed. Twist tightly. Insert the vehicle's wire(s), along with your newly installed positive wire into the openings of your new terminal. Tighten the allen screw down onto the inserted wire to make your connection. Slightly tug each wire to make sure you have fully inserted/anchored it. Place the terminal over your battery's positive post. Tighten the terminal to the post. Call someone who installs car stereos for assistance to complete the remainder of your installation.

With this installed onto the positive terminal, will I still be able to connect jumper cables, if needed?

I am not for sure, but probably not as it would depend on the height of your battery terminal.
[ Bob  May 17, 2015 ]
I should have been more specific in my first reply, you can but it will damage the terminal. I wouldn't unless like I described in my first response.
[ dipstick  May 17, 2015 ]
No, you would need a vehicle that has a remote jumper terminal like Chevy trucks and suv's or have a battery like a Optima with top and side posts.
[ dipstick  May 17, 2015 ]
I'd say yes because the entire terminal is metal so therefore its conductive
