    Main Relay Bracket Relocation?

    Hey,

    I'm trying to learn some more about this wiring that feeds into the main relay, fuel relay and O2 Heater Relay. I know this is an area of decay in my car. It's 30 years old and I'm sure there are some discrepancies in there.

    Does anyone have any advice on possibly re-positioning this? or just rewiring it? My car is intermittent when it comes to a few issues. Sometimes the injectors are loud af, some times they are so quiet. Sometimes the car runs great, sometimes it runs like shit without anything actually changing.

    Yesterday my fuel pump relay took a dive and it made me start investigating this area. The wires look like a mess under there. Is it worth just re-pinning? I can't find a lot of information on this specific area, other than which relays are what, but I'm looking for more.

    Any information would be greatly appreciated.

    Also, I have a replacement ground cable in the mail, so that could also be the issue...
