factory wiring harness wrap

[Pete]

Hey Guys,

Found lots on wiring with a search but didn't see anything re my question. What is the factory harness wrap? I've owned 4 Land Cruisers and all had black electrical tape wrapping the wire bunches in the sub-harnesses, except where one or two wires go to things like various lights that were in flexible conduit. i have no idea if or what parts of these were stock, if any. I'm not necessarily looking for an exact factory wrap, just something that looks decent and protects the wiring. If there is some kind of special tape, or special colors, that was used to wrap the bundles, I'd sure like to know about it, or I'll just keep using black electrical tape.

Thanks!
Pete

Everything on my 69 was black electrical tape however most new OEM lamp assemblies pigtails had a vinyl tubing on them sort of sealed near the connectors.

Hi,
I would recommend that wiring harness wrap should have excellent thermal dissipation, high quality moisture seal, high temperature and UL electrical listing. I used rubber based, elastic and heat shrink type. I doubt that factory wrap is the best.

This is called heat shrink sleeve and looks like vinyl. This is for new wiring.

I like Tesa 51025 tape and a fabric heatshrink tubing for the ends for a clean factory look.

I called it a vinyl tubing to best describe the fact that it is not heat shrink and to compare it to what Pete described as flexible conduit. It is thicker, and slides freely except where the wires exit and there it is crimp sealed.

 

[Aijaz]

So the size of the connectors on the wiring harness will determine the size of the vinyl tubing, right ?

there is vinyl tubing that you can get from mcmaster but the real score is the non adhesive harness "tape" that @Coolerman sells. get 3 rolls from him and you are good to go for the whole truck. cant recommend it enough.

 

[Aijaz]

some wires will get hot especially during over loads and faults so heat flow from harness wrap to outside is important. Are the connectors on harness moisture and dust
proof ? Can moisture reach the male female contacts of the connectors from the wire side ?

X2 for coolerman's tape. Great product.

When I rewired under the hood for my SBC conversion back in 1996, I used a product called 'Magic Wrap'. It looks like electrical tape but it doesn't stick to anything but itself. 19 years later, it is still in good condition... it hasn't unwrapped, broken down, or deteriorated... despite having been exposed to high temperatures under the hood and oil, etc. I'd previously thought 3M splicing tape I'd found more recently was better, however, I used some of it and it broke down in a few days and hasn't stood up nearly as well as the other product has after 19 years.

Yes, that's what I was referring to. It's not heat shrink.

I like what bikersmurf is referring to. Sounds like what I have used for several years whenever I tear into a harness or group a bunch of aftermarket wires together.

Has several names, but I use EXTREME TAPE. Easy to find on the net, not expensive and seems to last forever.

Self bonding PVC non adhesive tape. Coolerman, Britishwiring.com etc.

I used the stuff from Coolerman too. I bought extra. Glad I did. It doesn't stick to anything, holds up a long time. It's been about a year and half since I did my harness.

Another vote for Coolerman
