Thanks jwfirebird. My fuse box is aprox. 2"thick and 3 other modules are screwed into it from the back side thereby blocking the back side. Those 3 modules look like a wasp nest, just a series of 1/4" holes, some having wires going into them. So far I'm not having luck getting them removed from the back of the fuse box because the wires don't have enough slack to pull the module out. I can only pull them out 1/4" and I guess I need to pull
it out about 3/4" to get it out from the back of the fuse box. Still working on it to try and find more wire slack. Maybe I will try pulling all 3 modules at once to not need any slack. After pulling out the relay and not getting it back in, I am afraid to try this if everything pops loose.
