Fuse panel swap

Hi,

They are two very different components. You really should find one that is a direct fit. Otherwise, things won't want to plug in under the box.

Let me know if I can help.

Take care,
Joe

Being this is an 1986 it will probably be tough to find a used panel tagged for an El-Camino, however they used the same basic box layout in the Monte Carlo and the Buick Regal. That said if it burned up the connectors and the plastic you might want to consider replacing more than just the box. For that you could look at companies like Painless Wiring, American Autowire, Kwik Wire or similar. That would enable replacement of all of the wiring and eliminating the issues that caused the problem you have. Some of those companies also allow you to add items in that you may not have, like a power port or wiring for extra lights and have it be part of the harness instead of an add on.
As to using the 94 box, as Joe said it is much different as even the wire colors and connectors are different in the panel.
