Whats the "offical" line (from someone who's been thru the SVA) on loom covering?

How much of the loom has to be covered with tubing/ spiral wrap and how much can be taped?

Do I have to untape all my loom??!!

Mines a complete mismatch of both. Wherever I hadn't cut the bike loom I put trunking round and then taped the ends and periodically down it wherever it was bulging out.

I'm kinda of the thinking that as I've used most of the bike loom (and the only thing used on bike looms is tape), is it really necessary. I don't understand the need for it......

Is a reasonable amount of taped loom acceptable?

I have the bike loom but i have run it through conduet and when it comes out the conduet it is then spiral wrapped. Currtently the wires are exposed under the spiral wrap but im going to loom tape them

Yeah stick with your idea. I've only patched where needs be and in some places to make it look acceptable but nothing was mentioned at SVA.

there is no specific need to put your loom inside conveluted tubing, it is purely a protection factor in my eyes, i have conveluted tubing for where ever the SVA man can get his beady little eyes all of my engine bay,tunnel and rear boot tub loom is in conveluted tubing but behind the dash i have mainly just wrapped it in electrical tape, plus the tubing makes the loom look tidy and professionally done, which puts the SVA man at ease.

From my experience of the SVA, the examiner like all of the loom to be covered by something, but it is your choice as to what the covering is. I used a combinations of loom tape and convoluted tubing (tubing is easier over long runs)

The problem with tape is that when you want to add wires later it's a total pain in the arse. Same for spir-wrap IMO.

I used split-conduit for most of mine just with tape for short or fiddly areas of where it branches out of the conduit to stop it chafing.

My dash to rear of car wiring runs went inside the tough plastic tubing supplied with the Premier Loom. But I made sure I added extra wires inside that tubing to future proof for electric fuel pump or other rear electrics. All with unique colours (nicked from beemer loom).

Thanks guys, I've now spent all afternoon "tubing"!

Just got the difficult bit to cover - where they all meet up! Either going to need a 3" section 50mm in diameter or its going to get taped!

I spent some of yesterday doing some of mine.

I was planning one continuous run of split convoluted turbing, but ran round from OSF headlight to Transmission tunnel then left a gap as thats where my relays sit so loads of wires.

Where it bulges (there) and under steering column, i have put a second convoluted tubing over it self but in opposite direction and taped that one. Makes the loom look oval.
