Transmission Tunnel Wiring
The Baron - 18/3/06 at 06:05 PM

I may have dropped a clanger as I have not installed the wiring loom in the transmission tunnel to power the rear light clusters yet. Therefore I have not got any brackets or mounting points to secure it to. This is made worst as I have nearly finished my build, and don't really want to remove the engine, gearbox, prop shaft etc to install some mountings.

So my questions is, is it SVA acceptable to cable tie my wiring loom to my fuel lines, of which I have two, witch are firmly secured to a welded steel rail which runs the full length of my tunnel, or do they have to be separated?

Cheers in advance.

The Baron.

Keep wiring well away from fuel pipes

Don't run the wires near the fuel pipes! You might get away with them cable tied to brake pipes but from a safety perspective they should be well away from the fuel pipes.

Can't you just remove the tunnel top and drill and then rivet some cable ties bases to the top tunnel chassis rail??

You don't have to put the wiring in the tunnel remember!

Mine is running on the floor in the corner by the side of the tunnel.

I was going to say that too. Go dwon to B&Q and look at the aluminuum box section or tubes; see what diameter you need and then fit that along the floor/tranmission tunnel.

I'm just p-clipping trailer cable directly into the corner with no boxing in.

It's just run under carpet in production cars.

It's a deffinite No to cable tying to any pipes fuel or brake in the tunnel, but don't forget to use proper grommets when going through any panels if laying the wiring inside the car

Keep away from fuel pipes, its a SVA failure point on safety.

Protect your wiring with the minimum of Loom tape (not sticky tape), fix every 9-12" or so. I put my loom in split convoluted tubing for extra security.
In the tunnel, I used P clips on the inside of the upper rail so the loom "hung down", as you can drill the inside edges of the box section and just get a rivet gun in there as well.

Make sure it doesnt rub or chafe on corners (any bends), and is not exposed to heat (exhausts), or abrasions and is generally safe and secure.

7 core trailer wire?

I'm using 8 core trailer cable. It handily comes already insulated and protected and will feed everything in the back of the car.

def a fail as said earlier (first hand experience) i shifted the loom in the car park of the SVA. used sticky backed cable tie supports. good clean of the ally first, all still sticky 3 years on .
