    Wire Loom or Wire Wrap

    Hi, 

    =12pxFinishing up the long restoration.   Could anyone tell me what kind of wiring loom or wrap was used in the engine bay on a 1968 Mustang, and where to get it, or a reproduction?    Thanks.

    Re: Wire Loom or Wire Wrap

    You mean the stuff that wraps around all the wires?  Some people just use electrical tape, but that gets messy over time and looks kind of tacky IMO.  I did the entire wiring harness myself.  Chassis and EFI harness from Painless.

    https://www.amazon.com/gp/product/B004UHQ4E0/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
    https://www.amazon.com/gp/product/B00EH6IZ6Y/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
    https://www.amazon.com/gp/product/B005LTJ6TG/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1

    That tape and loom worked really well.  Same stuff they use in high end cars. The temperature range is well above anything in the engine other than coming into direct contact with the exhaust.  Take your time and it can look real professional.  Those push in cable ties were really clean and easy to use.  It made running the harness in clean paths along the fender wall a snap. 

    This is the exact same stuff as the professional car audio bundles the sell at 3 times the price and one fourth the quantity.  

    good luck

    Re: Wire Loom or Wire Wrap

    Not sure if the original was loom or wrap (tape?) on a 68, but I used a braided split wire sleeving on my 65 instead of the original tape.  This is available on eBay in several diameters, search by "split wire sleeving".
    If it was a black tape, note that this tape is not regular electrical tape that you would buy at a hardware store.  It is available from "Sherco-Auto".

    Re: Wire Loom or Wire Wrap

    Thanks.  I'm trying to keep it looking as original looking as possible.   I found this stuff, does anyone know if this is correct?   

    https://www.npdlink.com/product/wrap-tape-wire-harness-34-inch-non-adhesive-original/106731?backurl=search%2Fproducts%3Fsearch_terms%3Dwire%252Bwrap%26top_parent%3D0%26year%3D

    It says it's terminated it with this cloth wrap.

    https://www.npdlink.com/product/wrap-tape-black-cloth-34-inch-wide-x/144866?backurl=search%2Fproducts%3Fsearch_terms%3Dwire%252Bwrap%26top_parent%3D0%26year%3D

    So I guess you wrap the wires with the top stuff and then wrap the ends with the adhesive cloth to hold it on?

    Re: Wire Loom or Wire Wrap

    If you are concerned about originallity, those are the two kinds of tape that were used by Mr. Ford.

    Re: Wire Loom or Wire Wrap

    Great,  Thank you!

    TremendousWand that looks like good high quality stuff and probably a lot easier.   I'm tempted to do that and probably should, but am trying to stay as original looking as possible so will go with the stuff from NPD.

    Thanks again

    Re: Wire Loom or Wire Wrap

    The cloth tape looks like 3M’s friction tape that you can pick it up at Home Depot.

    Re: Wire Loom or Wire Wrap

    I just use 3M Super 33 electrical tape.  It looks like what Ford used.  Its very good tape that does not seem to break down due to heat or unravel like cheap tape does.  If you have to peel it back there will be residue on the wiring, but that's the same for any tape you use. 

    I did use some corrugated plastic split loom in the trunk for my stereo wiring, but wouldn't use it in the engine bay where I prefer the stock look.

    Re: Wire Loom or Wire Wrap

    1/4" loom is usually used for single wires, maybe 2-3 if the gauge is small.  There is 3/8 loom.  Its not uncommon to see it with 5-6 wires in it.  1/2" if pretty big, used for 10+ wires.  3/4" is used for main harnesses in EFI applications where you can have 26 wires or so coming from an ECU connector.  Remember a minor change in diameter makes a big change in surface area.  1/2" loom has 4 times the space in it that 1/4" has.

    Re: Wire Loom or Wire Wrap

    There is a 3m product and others out there called friction tape. It leaves no residue if removed. It really works nice for harnesses. There are many options for wiring protection. Another option would be split wire loom either corrugated or split woven loom. I can talk to my buddy but he has a source for factory style high heat woven loom. Looks factory and works nice on looms with some friction tape for joints.

    Re: Wire Loom or Wire Wrap

    I like the 1" non-adhesive PVC "harness wrap" for areas where split woven loom doesn't work to my liking.  I use adhesive lined heat shrink tubing to terminate the split woven loom.  That works well and looks very "finished". The non-adhesive harness wrap is very close to what was originally used.  The woven loom is not anything like original but looks way better IMO.
    A couple of sources I use are:  Terminal Supply for the woven loom, sold by the foot.

    Re: Wire Loom or Wire Wrap

    Great information.

    I don’t have first hand experience with it.
    I read somewhere that there is a non adhesive type tape used for powder coating as well.

    My remembering thingy on my shoulders ain’t what it usta be.
