[QUOTE="toyodaaddict, post: 1570222, member: 18655"] Here is a little update on this, almost a year later. I re wired the ALT and fused the main power wires with MIDI fuses. I upgraded the charge wire to 6 awg and ran it and the sense wire to the power distribution bar, where everything is fused. I also Added a Blue sea fuse block (part 5045), that I will use to power any accessories I may add. [img]https://i.imgur.com/nyPStjHl.jpg?3[/img] I found some of the soldered joints from the EFI swap where not looking so good. I'm not sure what exactly caused this, lack of marine shrink tube, mildly corrosive solder possibly? [img]https://i.imgur.com/jmGa427m.jpg[/img] I stripped down the harness and re did all the joints with BMW butt connectors and marine shrink tube. I also put a small shot of kester 245 no clean solder in the center where the wires come together (not shown in the pic). I was worried about using a solder that was possibly corrosive, so I contacted Kester. This was the response I got. "44 is a good general purpose flux but for an automotive application I would recommend the no-clean 245 over that if you are just soldering copper wires. 44 is rated ROM1, where 245 is ROL0. If the residues are going to see the heat and moisture associated with automotive you will have a lower corrosion risk with 245. I’m not saying that 44 WILL corrode, it’s just that 44 is a stronger flux and there is a lesser risk with 245." BMW connector part numbers 61138353746 - 0.2-0.5 MM² 61138353747 - 1.0-0.75 MM² (16-18 gauge) 61138353748 - 1.5-2.5 MM² (12-14 gauge) 61136931481 4-6 MM² [img]https://i.imgur.com/XmU82VIl.jpg[/img] [/QUOTE]
