i have a mercury mystique gs wiring harness and i need to replace it so i was thinking why not copy the same layout as the old one i found one at junk yard thats fairly good shape i mean it doesnt work but i can copy it to make a new one so im wondering if anybody can direct me to how i can make one that looks and works exactly the same as a brand new wiring harness see if i had the option to buy a new one i would but they dont sell them anymore so im kinda stuck at this difficult decision
The hard part will be finding all the special connectors. Then it boils down to making sure that you match the pins at both ends. You will have to use your own color coding or also do a lot of research to find the right colored wires. A soldering pencil that works on resistance is a handy tool, but a gun with a sharp point will do or a pencil iron. It is more work then I would want to do, but considering the cost of a replacement that is custom made it will be much cheaper. Some items are not in the system by the way and are what are called depot parts, which means that they are maybe a month away. A lot of parts persons don't know how to find obsolete parts, so maybe try a different dealer who as a real parts-man who can find what you want.
be metculous unplugging every thing marking what goes where , write it down as well as the colours , when you have it all out , lay it on a big sheet of butchers paper or similar grab some colour texta's , trace it all out , then lay your new stuff out on your pattern tape it up , plugs could be a problem , i'm not sure where you are , so i can't recommend a supplier . take notes of what terminals went where take pix where possible
