Hey i want to upgrade the alternator wires to thicker gauge wire and i was wondering what other people have done with there wiring, the reason i ask is that the white power wire from the alternator to the fuse box has a big crimped and soldered terminal on the fusebox side which has a very thick black starter motor wire and the white alternator wire together in that terminal and it is angled to fit perfectly so im not sure how to remove the white wire and add a nice new 8 or 4 gauge alternator wire to it, im also not sure what gauge to use cos i read that 8 will to upto 100amp but i thought of using 4 gauge cos i got a few 4 gauge terminals and wire laying around but im worried that its too big so what ate your thoughts on what gauge wire to use and on how to connect it to the fusebox side?

i will include a photo of the terminal im talking about and yes i will also do the earth wire as well thats an easy jobpost-229-14183315918651_thumb.jpg

The good news is that change is dead easy. Just use a second terminal on the same stud (or the other one, they are connected by a metal bar) for the new wiring. Cut the old wiring as close to the terminal as possible and wrap well with tape

    • Hopefully it ends up being something manageable, like a hone, rather than a full bore—it would be a huge relief if it’s not as bad as it looks. Hang in there; these setbacks are annoying, but it sounds like you’re handling it as smartly as possible.
    • At the end of the day, it’s all about understanding the odds and being comfortable with the potential cost, whether it’s horsepower on a build or chips on a roulette table. And I have to say, the Laine example made me laugh—some people really do embrace that carefree, “roll and see” attitude!
    • Thanks MBS206, i got that PDF but got abit overhelm with all the connections and tracing of wires. I wasn't expecting to plug the dash harness anywhere. i was just going to use my electronics jumper wires to plug into the right pins like ECU power, ecu ground, ignition trigger etc... I do have a few ratchet straps locking it down tight. Fire extinguisher ready and only a small amount of fuel at a time, enough to submerge the pump.
    • Thanks GTSBoy, i will do abit more digging. I am missing a blue relay near the ECU connector... so i will chase that up in the next few days as well  
    • https://yariksteel.ru/manual/R33/Skyline_R33_elektroprovodka.pdf   Page 18 should be what you want for the Dash Cluster wiring. Though, you don't need the dash plugged in to get the motor running. What you want is power as how GTSBoy said. You need to power the ECU. Find in the above link the ECU pin outs (Verify them before just connecting them up from things written on the internet). Find anything needing power, give it power, find anything needing ground, give it ground. Then give the starter motor power through a big cable, and bridge the solenoid on the starter straight to power too.  ECU will be on, and when you give the starter power, it'll spin the starter motor, and it should start. I also hope you have a proper stand, and not just the engine sitting on some wood. You will want it bolted down properly.
