You need to tie into the top cooling lines coming out of the radiator. Are you going to use rubber hose? You might need to cut the line and install the cooler in-between the cut part. You will need to find a hot that is switched (hot when the switch is on) to use for your cut out power. Maybe the radio feed wire/fuse will work.
