Painless Dual Battery Kit Install Question

[BIIHawg]

I am in the midst of installing the Painless dual batery kit in my 89 Bronco II and have a question. I need to tie the system into a wire on the truck that is HOT in the RUN and START positions. Does anyone know what wire i can tie into and its location??? I'm hoping to save time by asking the experts on here as oppose to searching around on the truck.

Thanks in advance

As long as it does not have to carry much load the plus side of the coil would work.

If you have power windows they're hot in run only. Also the fuel pump and the radio. But it's not a good idea to pull a lot of current through them.
