well one of the goals for my car this year was to clean up some of the wiring, and i was looking around on the internet and stumbled across this place in florida that sold some braided nylon tubing www.cableorganizer.com . and decided to give it a try here is my write up.
braided nylon tube in whatever size you may need
flat head screw driver
this is how my coilpack harness looked when i started.
here is the material i used.
i bought 1/4" and 1/2"
first make sure you make good notes on which wires go where in the plugs because unpinning them is the next step
then to unpinning, to do this particular plug you must first take the inside cover off my gently prying back the prongs that hold it in, and push the cover off from the botom.
then do the same thing to each of the wires and slide them out of the bottom of the plug.
after i did this i cut the old jacketing off of all the wires, it should look like this when your done.
then i go through and put electrical tape around the wires i am going to cover ( you can go without this but you can see the colors of the wires through the nylon braiding)
slide the the braiding over the wire, and figure out what length to cut it at. cut the braiding and slide it back on.
then get a piece of shrink tube and cut it to your desired size slide it to the end and shrink it.
after this you go back to the plug end of the wire and put another piece of shrink tube on shrink it, and put the plug back together.
thats pretty much the basics. here is what my harness look liked finished.
and a before and after
