Ex, I was looking thru another post and you recommended a junction block from del city. looks like you mount on the firewall and connect the positive battery cable to the inside and have power in the engine bay, but it says 250 amp max, I am assuming that is from the different parts connected, fuel pump, fan, waterpump, etc, as the battery alone has 750+ cranking amps, but I don't want to assume too much. This looks like a good option if my assumption is correct. ...wannabe
