P1000 Length of Cable from #2 Battery to Engine ground.

[UKNB]

Im thinking of running the negative from my 2nd battery back to the engine. I see where the main is grounded, and I think there is another location in about the same area where I could bring my #2 battery negative. I read a few times here that "you cant have enough ground". Or can I just double up on the primary engine ground? My SxS is at my camp and I want to bring a cable with me this week to finish the job and I dont have a measurement.. can anyone tell me how long a cable I need to run from the second battery to about the same location of the the primary ground. I just plan on buying a prefab cable and Im not wanting to coil up 5' of unused cable if I dont need to.

Thanks in advance

Factory ground black wire with blue tape in mid right or ground to the frame next, left of second battery.
Do some dual, second battery searching and you will see many explanations and illustrations.

Yup, That is the ground I used for my second battery. Honda already ran it for me.

I also used the preinstalled winch ground to connect to my 2nd battery. Then I have my winch cables directly to the 2nd battery.
