    this may be a very dumb question, but I was having trouble finding a clear visual or description on what the factory entry point for the + lead into the fuse panel, brown wire, etc junction actually is. My car has 3 wires (2 from battery & brown wire to I presume ignition) joined with a wire nut. Remarkably, this works and has not been a problem source yet as I've been sorting things out little by little...but it's time to clean it up. At the very least (or temporarily), it will be soldered and heat shrinked. Would a power distribution lug of some sort be better? I'm guessing this is also where I need to pick up the feed for relaying the low beams (can't say I know where the + for the factory relayed high beams is sourced). Guess I'd like to know what others have done with success for this. Clearly the wire but thing was effective enough for whatever issue the PO was having, but it's a little too much for me to leave as is! Thanks in advance.

    On the '85 to '88s, the large gauge brown wire from the battery went into a 4 spade terminal block attached to the bracket that holds the 6 relays to the left of the fuse/relay panel. One of the wires that comes out of that goes to the fuse panel for unswitched 12V and the other goes to the ignition switch for switched 12V. The amount of amps going through that block created lots of heat and can melt it, so a PO probably swapped it out and just tied the three wires together with a nut. Here's a picture of the fuse panel from a used one I picked up. You can see the black junction box on the front of the 6 relay holder. IMG_0527.JPG

    Here is a close up of it showing the meltdown.

    This is the rational behind the brown wire mod. It is best to get a power distribution block with fuses to supply power to relays for the headlight mod, wiper mod, etc.

    Thanks. Okay, that make sense on all levels. Don't know how many circuits I would end up wanting to relay but having the option in a clean way is desirable.

    Currently, the serious Xheads in DCfiats have relay kits for their wipers, the headlights and the electric windows. In an ideal world you probably don't want current directly from a Fiat ignition switch to anything.

    I appear to be getting serious & I have a car with their sticker on a window, so maybe I need to get on the ball here! I believe the '85 already has relays for high beams & window motors. I should not say anything about the wipers on this car for fear I will jinx them, but suffice it to say that I have not had concerns about wiper performance. Switch wiring capacity noted however.

    So, do those serious Xheads install a nice input/distribution block in place of the problematic connector that seems to melt per factory spec?

    This is what mine looked like

    I added an extra feed from the battery terminal and crimped them all as one

    I ran an 8 gauge wire from the battery to a new distribution block took all the wires that were in that plastic square junction box and hooked them to the distribution block.
