Quick and easy power hook up ?

Hey eveyone .. I am looking to tie in some temporary power conenctions to the back fuse block under the seat. It is only to power some temp lights. 2 questions ..

I have a ground loop/ring (yellow in color) that I should ground via a bolt. Where is someplace quick and easy to bolt this too to ground it that is near the seat or fuse block?

second is power, I am not worried about fuses as I have inline fuses to the switches. It is the equvalent of about a single 10ga wire for power?

Any help would be apprciated..

I saw the power cable but was not sure ... thanks for confirming that .. do I have to disconnect the batter before tapping into it? Also, the ground looks kind of iffy as I dont normally like my power and ground that close to each other? Do you know of like a seat bolt or something else to ground too? If you think it is safe will go for it .. thanks for the info.

I have to suggest disconnecting the battery first, but Ill admit when I tapped it I didnt.....and yeah that ground does work just fine....the problem with the seat anchors is that the bolts are too big for a ring terminal:m2:
