The problem I have does not involve accessories, the problem is that the power stays on to the fuel pump and the cruise control with the ignition off. I have replaced almost everything but haven't found the problem. any suggestions?

Okay, it sounds to me like you have a short to power in the A/C circuit somewhere. The A/C and fuel pump do use the same circuit. I am sending you wiring diagrams for both. Let us know what you find out. Thanks.
