This is something I have needed to do for a while. My under-hood accessory wiring looked more like tonight's special at the Spaghetti Factory rather than competent wiring. What I needed to do was organize and consolidate my fuses and relays. I stopped by AMC Salvage in Glendale to see what Nacho could find for me. We found a fuse/relay block from some old Jeep that he had cut the harness off of for another customer.

When I got it home I carefully removed all of the relay contacts and set them to the side. Next I drew up a plan to re-wire the relay block to suit my needs. I seperated the contacts from the wires and soldered new wires to the contacts and inserted them back in the block. I left the fuse contacts alone and used the existing wires. All I had to do was route the fused leads to the correct position for my relays. I have still have 5 fuses left for future connections that have been taped off and secured.

I chose to mount the block above the battery on the ECU cover. I used heavy duty 3M double sided foam tape to secure it. I like the 3M foam tape because it holds very well but will remove when you want it to without leaving sticky junk all over the parts. When I need to add new circuts or service the block I can remove the tape and flip the fuse block over for access to the contacts and wires. I mounted my Optima on it's side and used a 1 ft battery cable to connect the block to the battery's side post.

I ended up using all of the relay contacts to wire the block but I still have room for 3 more relays. When I need to add more I can go to the U-pull-it junk yards and remove contacts from another car and use them in this block.
