Because of where I want to mount my ignition coil I need a ignition lead that is about 95cm in lenght. All my local motor factors can't get a lead this long. Does anyone no where I can get one? Or get one made? I realise a lead of this lenght isn't ideal but I really dont want to have to move the ignition coil.

Give WM Rollings in Wrexham a call, or tweeks?

google vehicle wiring products you can then get the bits to make the cable yourself (or see if they can do it).

incidentally where the hell are you mounting the coil pack if you need a Meter of HT lead?!?!?!?! and you had better spunk the cash on GOOD cable as the loss down that will be emmense

Welsh Dan - Cheers. Will give them both a try.

Stuart - Ignition coil is behind the scuttle panel. Its the way I would like to route the lead to it that is the problem. Cheers for your help.

Staurt - Just had a look on vehicle wiring products website and they have what I need. If the lead starts to cause issues then I will look into re-routing or moving the ignition coil. Cheers.

dont forget to gromet the hole in the scuttle you pass the HT lead through. And make sure no other wires are near it

Sorry for the stupid question but why do I need to make sure no wires are near it?

I would assume so you don't get electrical interference mate.

As suggested by Stuart, try here http://www.vehicle-wiring-products.eu/VWP-onlinestore/htterminals/htterminals.php

due to the length of the cable, the Voltage will want the path of least resistance. Now new GOOD HT cable shouldnt let the voltage out, but there is a change on such a long run that the spark voltage could jump to the chassis/other wires nearby simply due to the resistances involved.

It might not pose problems, but better to think about it a bit first incase :D

All lies lol. My 360 Lolvo runs an 855mm king lead as standard and I get no issues. Fair point though, would have to be some **** cable to 'escape' as you say lol

I know, but having been in the automotive game long enough to see some hillarious errors caused by "escaping" signals, I always like to be over cautious now :D
