    There's no convenient black negative terminal under the hood, as far as I know. Connect the black lead from the donor battery to a substantial bare metal part.

    3G has ground wires connected to the inverter housing, so that would be a suitable point.

    2G has the strut mount bolts behind the main relay/fuse box next to the inverter, and the one facing forward is a convenient grounding point.

    So I did this too, checked twice, wondered why it looked wrong, then hooked it up anyway and the fire works and horn and lights on ensued.. I am having trouble accessing the right screw, I purchased a fuse box from a wrecking yard, the fuse box was perfect, (I knew i was going to need fuses and relays and practice pulling the box apart)
    I got the donor box open but the right bolt is unassesable. Sergey, does the fuse holder area break apart so you can pull part of it lower? here is a pic of the screw i cannot reach. and I don't know how this would come out if i was able to unbolt it. I know i could cut it out, but It wouldnt do me any good if i couldnt then access the one inside, I am looking for advice on how to pull this box apart more so the "fusable link" can be pulled out and then how to insert into my cars box.

    RESOVLED,
    there are 5 clips on the inside of the box that allow the center section to lower.
    and a pic of the fuse. this one.jpg 69675468_530567190843424_4228001862432849920_n.jpg

    Hello,
    Great information, I hope to try this myself this weekend. Do you have the part number for fuse?

    I don't have it, I thought i did more damage than just the one fuse, so i purchased the whole box from a wrecked one on ebay. I think its one you have to purchase from the dealer too, I looked online, and the I couldn't find it in online dealer sales.
