Electrics through trans tunnel????
Done loads of searching on here, but what's the best way people have routed electrics through trans tunnel? I have brake line on top drivers
side, fuel on bottom passenger side. Plan is to run electrics on same side as fuel but at top. Any issues with this??? Some pics of what you have
done would be very useful.
Cheers,
Matt

i can't really see it makes a huge amount of difference, but i'd put it on the same side as the brakes.
on my car, i'm actually running brake lines and electrics inside the cab, because fuel and exhaust has to go in the tunnel

ive done it top of the passenger side, just make sure that its securely fitted, nothing hanging that could catch the prop say. Either use the cable
tie things riveted in, or use p clips.
Shouldnt be a problem

Same as mine, ran the wires along the top opposite the brake line. Wrapped in spiral and split convoluted stuff...

Description
Brakes and fuel down one side, and my electrics go down the other side (all at the top). No problems with their routing, despite a prop failure!

This may be a stupid question from someone who doesn't know a whole lot, but could you run the plumbing through the chassis members?
Would make for a pretty installation I think, a beast to re-wire/plumb though.....
I'm not scared!!! I'm just marking my territory.

The issue with running in chassis members would be how to get them in and out, knowing that the tubes are all welded to the next tube and are
therefore closed....

I would have thought running through the chassis would be difficult as how would you fix the pipes in place to stop them chaffing on the inside of the
chassis rails. Also diagnosing faults would be made more difficult.

Depending on the amount of cables required at the back a 7 core trailer light cable could be run down the tunnel as suggested well out of the way of
the prop. and fixed with p clips or cable tie mounts.

Here's my layout, brake line on the bottom, wiring will go opposite on the bottom, fuel on top rails

I saw a lcoost racer the other day which had plastic plumbing pipe fixed in the transmission tunnel and trailer cable running through it.
The big advantage being that the cables can be pulled out really easily in the event of a failure without having to take the whole car apart. Quite a
neat slution really, and the wires were well protected too.

i'm going to put my fuel hose through it in case it ever splits, so it just runs out the ends of the pipe, insead of spraying over exhausts and
stuff

You can get up to 13 way trailer cable, but for the cost I'd run 2 lengths of 5 way thinwall multicable.

Not sure about IVA and using plastic pipe, as the cable will move around inside as the car corners (unless the diameter is very close) and eventually
fail. Fine for racing obviously due to the much lower mileages.

Wire, on the same panel, should be mounted above fuel and hydraulic lines.

Mines as you propose.. Just keep the wiring tidy, and held at regular intervals (<30cm I think)..

Looking at your photo it looks like you are having a type 9 gear box like i have if so i found it best to run the wires on the o/s because the revers
switch on the box is on that side

Keep the Fuel Lines away from ALL Wiring.
It was a FAIL Point for the SVA, and probably is too for the IVA.
Fuel lines and sparks do not mix well at any time, let alone in a accident.
I put my Fuel line and wiring on opposite sides of the Tranny Tunnel.
You know it makes sense!
Just my 2d's worth.

2. Never take life seriously. Nobody gets out alive anyway.

Thanks to all so far....plenty to think about.
Jacko (or is that Clouseau)....you're right I am running a type 9 and o/s would make more sense but wiring would then be on the bottom...is that
OK? Also, how did you determine I was using a type 9 form the photo??
Cheers,
Matt

I have a Indy too and i can see the same gear box mounting plates on your chassis 
I cant see any reason why you cant put the wiring at the bottom its away from the fuel pipes

if i were to resurrect the build and start wiring, i would have multi pin connectors at the front and rear bulkheads, making the loom in three
sections. This way, fault finding would be really easy, and replacement simpler.
The conduit for the cables is a great idea. MEchanical protection in the event of a prop failure which would also take out the fuel and brake lines.
Id run the fuel and cables seperately in steel conduit though.

i think the idea is that if you're going to get a fuel leak, its going to drip down onto the electrics, insulated electrics...
but look at your carbs/fuel rail, whats underneath? a starter motor. and yes i've had a leaky fuel rail on my old bmw, pi$$ed fuel all over my
starter motor. always took a deep breath befor starting it lol
can't see its a fail point, but thats the thinking behind it anyway i think

What about an injection fuel pump, that has high pressure fuel 1" from a 10A + supply!
