Hey guys,
Today me and some mates installed coilovers all around on my JZZ30 Soarer and it went well.
Obviously we lowererd the car a bit TOOO much, after a bit of a drive around I could feel the front wheels hit the wheel arch and scrub while turning and when we hit bumps in the road.
Speed bumps were a nightmare the whole underbody just scraped horrendously.
I drove it to my nearest Tyre and Wheel Centre so they could adjust it and raise the height and do a full wheel alignment.
When I got there the guy started my car and it wouldn't start then he showed me this whole heap of wires that was sticking out of the drivers side wheel arch, yes there was some sort of loom running through there and now it is a frayed mess (no wonder I had all these wierd jap word warning messages come up on my dash).
The car does not start and will have to sit there till Monday when an Auto Electrician can come and look at it.
Now the question is what to do ???
can this be easily fixed or can I buy a new loom thing from a jap wreckers, approx how much ?
What would be the best thing to do ?
Thanks guys |

That would depend on how many wires copped it. If it is only a few then repairing it should be nice and easy. I can;t quite remember how many wires live down there, it has been a while since I have delved under my guards.
A whole loom (can't see a wrecker just selling you the bit you need) can run into some high figures, shop around.
Should've searched! Plenty info regarding the perils of lowering the car to much affecting the loom. In fact, you might even find how to fix it! |

Fixing isn't an issue, just time consuming joining each wire that was damaged.
Their colour coded which makes it an easy DIY job for anyone with a soldering iron and some heatshrink (NOT ELECTRICAL TAPE!!!!!!!) and half a brain.
The problem comes from what was shorted out while the wires were touching the chassis or each other, ECU's etc aren't too fond of being spiked.
But that's a worst case scenario.
I've rewired a few customers cars in my time, and only one had a damaged module due to wiring being rubbed through and shorting to ground.
If you do it yourself, remember to stagger your joins as much as possible, prevents any sharp solder dags piercing the heatshrink and creating a hard to find problem. |

Yes Ben I used searched and stuff yo didn't find my answer so I created a thread !!
Thanks Sean, I think Ill get da auto elec to solder it all back up.
I just hope the ECU didn't fry !!

Just be thankful its not an airbag car!
That trick usually costs the two front height sensors ($350 ea) and often the suspension computer but it's normally fixable. The SRS airbag crash sensor wiring cops it too as well as lot of other sundry wiring. It can take days rather than hours to sort out and new looms really aren't an option. Too much disassembly of the car to fit them.
I'm not sure what wiring is there in the TT's and pov V8's. I wouldn't have thought it would kill the car though.
I'd be checking power feeds generally. It may have taken a fuse or fusible link that feeds somewhere else too. |

ouch,.
tough job.
SO is there a way to re-route the wires so they dont scrub out ? |

Tell me how you get around it Rob. Been trying to figure this one out for ages. The only option I can see is to cut the loom in half, re-route it somewhere else, then wire it all back up together. Unless there's some simple plugs somewhere? |

that will be a last resort.... i'm hoping they can be tucked up high enough to be out of harms way.... if not, cut and move it.. there cant be that many wires in there.... |

You can shift them up and sideways a bit in cars without the SRS airbag. With the airbag wiring you have to get it out of the loom (easy it's only taped in places) and shift it separately WITH THE BATTERY OUT OF THE CAR or you could set the airbag off. Especially if that wiring is damaged. Airbag wiring is long enough and there are even holes in the right places, to go through the engine bay.
I've only ever seen an airbag set off once like this so it is possible but not really that likely. Pulling the battery out is good insurance but remember the actual airbag itself can go off unconnected. It doesn't need power to go "Bang". |

I've only ever had to cut and shut where the loom is actually so badly damaged it needs a section cut out.
You can get the loom up past some moulded plastic thingos that are above the top inner guard. I reckon that's good enough as it'll hit that first. I even try to get a plastic inner guard on them if I can as it can be made to sit up a bit with the loom moved and doesn't reduce clearance much. Wear marks on that are a good pointer as to what's going on and you shouldn't be low enough to wreck it if it's been carefully fitted.
TT's are a bit different in that area and I've never had the inner guard to put on one so I don't know for sure about them.
The biggest problem on lowered airbag cars with big (20") wheels is front to rear clearance in the arch.
Basically the wheel arch isn't wide enough for 20" wheels and you can't get a tyre low enough in profile to fix it. 19's can be made to fit.
Running higher height is the only way to fit 20's without busting stuff and in airbag cars it gets expensive.
This is why you can get away with 20's, just, on a standard TT but not an airbag car.
The TT sits higher. |

If it's at the top rear outside then shifting the loom will fix it or at least improve it. |

Well I REALLY need to move mine either way. The loom cover has been completely chewed through. Only a matter of time before the wires inside become damaged.
Guess it's just part of owning a lowered car on 20's  |

Late models are a bit different. The front bar design and some others gives them a bit more but 20's is still pushing it.
Most problems I see with airbag cars is trying to run them low with big wheels.
Most don't understand how my car can be an inch or two lower again with no problems at all.
Wanna buy a perfect inner guard? I got 4 complete ones on my car. But, no I won't sell them.
I use Supra wheels not because I like the look but because they are a perfect fit. And OEM Toyota quality. And I can get full suspension and steering range with no interference at all.
That's also why I have a stock bar and only small sideskirts. Not for the looks.
Maybe a good set of 20's that are the right offset and otherwise correct fitment could work too but I've never seen any. |

Mark, I just spent a good 2.5 hours trying to fix this problem. What I found was that my FMIC piping was positioned so that the wiring loom was actually pushed OUT towards the wheels causing it to push out the guard. This caused my wheel to chew through the inner guard, 'til it got to the wiring loom.
Fixed this by taking off the particular FMIC pipe and re-adjusting it so that the wiring loom actually sits BEHIND it, hence NOT pushing the guard out towards the wheel. I think it's a bit too late now though, as the damage has already been done 
P.S. My wheels are +45 offset  |

You may get away with the right tyres and 45mm offset and a custom alignment but the steering geometry and front suspension are designed to work with 50mm offset.
I've heard people say that 5mm isn't much difference but try altering your toe-in by 5mm and see how long the front tyres last.
5mm in steering geometry terms is huge.
Oh, and your brake fail box is here and modded.
I have an old stuffed one somwhere too that I can use the socket from to make a shorting connector so the tail lights will all work without the box if it isn't right. That way it won't be so much of a pain if the box has to come back again.
I have a few problems doing the fail boxes for cars that I don't have spare tail light looms for.
if I haven't got the car here then it can be mostly guesswork and the box won't be right the first time. No great drama they're small and postage is cheap. It'll be right eventually. With the shorting connector to get everything working while the box is out there's no real problem.
Given that a new one from Toyota will be in the $300+ region and they may not have a model that will work for the particular setup the modded one is still cheap with a bit of extra postage added on.
And Aussie Post are nice people and deserve to be supported.

Not like postage will cost you an arm and a leg. That's what Toyota likes to do to us
As for the box mate, have you sent it out yet?
Tried sending the money last week but it got denied? E-mail me with your bank details again so I can pay you already! |

Yes, my bank account was attacked last week and all the defaults and passwords changed.
Thanks very much whoever that was. Wasted your time but didn't ya?
It should all be good now.
I was hoping to get hold of a late model car to plug your box into just to be sure but I can't seem to raise him. It'll go off in the post tomorrow either way. |

Whoa! Did they take anything out of there?
Makes me want to change my password every fortnight now..
Don't worry about testing it mate. If it doesn't work I'll just send it back to you again haha |

Bastards didn't get anything but they sure stuffed me around.
Mainly 'cos I'm broke and there's nothing in there. |

I set up a separate bank account for dealing with people. Any money going in gets transferred out to a high interest Internet only account, and I only put money back into it briefly if I need to make a payment.

Exactly, that's why there was nothing in there.
And before you say
"Exactly what? was it a payment account or just nothing in it ?"
The answer is "Both" |

Happens to people all the time here in the USA with lowered SC300's.
You can unclip it from the body and zip tie the harness up above the frame rail. Instant fix and it will never rub |

Richard, can you show me where the clip is mate? I had to take my Intercooler piping off in order to move the loom. Luckily for me it was as simple as the IC piping pushing the loom out, so simply placing it behind the piping solved the problem for me.
No more *CRUNCHING* noises when I turn |

Works for the basic models here but the more factory extras the harder it is. And I just don't want to talk about shoddy add-ons.
Airbag cars with the lot or Actives take a bit of loom re-shaping (unwrap completely and tape up again leaving some wires out to re-route entirely).
Results vary a bit depending on how good you are and your attention span. |
