When making up a car wiring loom. What are peoples preferences?
a) Cloth harness tape, b) self amalgamating tape, c) heat shrink sleeving d) Something else or e) a combination of the above.
Thanks
Mike

Twenty odd years ago I wrapped mine in dry insulating tape. You can get a good tension on it. It still does the job and looks well.

Surely the answer to that question is to use what's appropriate for the age of the vehicle.

Back in the 1980's we regularly sold hundreds of rolls of non-adhesive pvc tape to a company who manufactured wiring looms for their custom heavy trucks. Made by Advance tapes, UK.

I used "loom tape" when I rebuilt the loom on the Firenza, aka non-sticky insulating tape. It's what the car had when it was new, so I wanted to keep it original.

The only trouble I've had is with the outside ends of the tape - apparently it should be possible to just pull the end of the tape a little and let it back against the previous turn and it should stay there, however mine was just unfurling so a little spot of glue on the end stops that.

As goneps said, though, the best thing is whatever it had originally. And don't use actual insulation tape.

Depending how many wires are in each bit of the loom (e.g. the main trunk tends to be the thickest) then use loom lacing to hold it together and then enclose in either cloth or non-adhesive loom tape.

Loom Lacing, now that's something I haven't heard of for a number of years. In the 1980's I spent many hours repairing or making wiring looms. We used to use either lacing cord or self amalgamating tape depending on installation and use. If your methodical with your layout, both will look profesional and neat. Theres nothing more satisfying when it's finished than to see the wires running straight and true throught the loom. Very Happy

Hi: Thanks for reminding me about lacing. Been there, done that, in my early days as an electrician in the mining industry. Then came "spiwrap".

Must have wound on thousand of yards of that stuff.

Regards

Peter
