MKIII 1JZGTE Swap How To! Pic Heavy

Now this is the part you have all been waiting for!!! The harness

Things you will need.
-Enough wire to extend the harness 18" i Cant remeber the exact size but I kno i got two sizes for the thick power wires.
The smaller gauge i used was bigger then most of the wires but i wasnt about to buy 30 diff sizes of wire! Now remeber you can Upsize wire but not downsize it! so Always go bigger not smaller!
-Soldering Iron (preferrably adjustable heat)
-Solder I used .028
-Solder flux.. Liquid is alot easier to deal with!
-Alcohol... to clean remaining flux from wires(its a corrosive)
-Heat shrink and lots of it!
-PRACTICE... Get comfortable with your soldering before starting.
-Heat gun for the heat shrink! I dont like using torches
-Its a good idea to have some solder removal wick!
-Anti wicking tweezers. you need two of them. http://cgi.ebay.com/2-Pc-Locking-STA...item35a7d14ab3

Some Pics

Now how i did it...Mainly for the ease of troubleshooting if ever needed and ease of assembling harness I separated harnes into 4 chunks of wires before cutting it.. carefully makin sure there is not multiple wires of the same color in the same bundle! then labled them 1-2-3-4 I labeled them twice with enough room to cut them in the middle.. that way when its cut both sections are labled. I also did each bundle in a different color of wire. and mad enote of what color is in which bundle.



Then ya cut it.


Now some people say to cut the harness at multiple location so it doesnt bundle up! but the fact is... it wont bundle if you solder correctly. Your solder connection should not be thicker then the wires insulater. I separated the bundles from each other and one bundle at a time i stripped the wires and slid on the heat shrink on all the wires so you dont forget one.



I labeled each and evry wire on the extension so i knew what it went to.. and i traced it when soldering to make sure i labeled it right!!! I didnt want to do this twice
