Hi,

It has been a long time, but I'll try my best to help. Please understand, I don't have a wiring schematic of the vehicle, so this is nothing but from memory.

If I remember correctly, there should be several fusible links that run between the battery and the power supply entering the vehicle. Additionally, if I recall there is a connector on the firewall that will have two wires going to it. It is a form of fusible link. It was only about 2 inches long. See if you can locate that.

Also, if you can take a few pics of the wiring under the hood, it may help me remember better.

Let me know.

Joe
