Blows fuse #24 30amp

A simple trick to finding a short is to replace the blown fuse with a pair of spade terminals, then use small jumper wires to connect them to a 12 volt light bulb. A brake light bulb works well. When the circuit is live and the short is present, the bulb will be full brightness and hot so be sure it's not laying on the carpet or against a plastic door panel. Now you can unplug electrical connectors and move things around to see what makes the short go away. When it does, the bulb will get dim or go out.

To add to Doc's answer, if those wires were shorted against the manifold, that probably caused wires from that circuit further down the line to melt together so you have only found part of the damage.

As long as it' s not an intermittent problem. That is the REAL long way of diagnosing a problem. You wouldn' t want to pay a mechanic to troubleshoot a problem this way. What are you trying to solve?
