The engine wiring fuse panel is the same item that’s used on the LS series of engines. I’d hoped to install it on the firewall, but there just wasn’t enough space available, so it ended up on the passenger side inner fender well.
One of the great features with both the LS and LT engine management systems is that they take control of all electrical requirements including both the fuel pump system and the fan(s). On the LT engine there are two fan controllers whereas on the LS there is only one with the stock harness. After the main battery/alternator/starter feed is connected any additional electrical demand is feed into the body wiring fuse panel.
