  • Reverse Voltage Spikes & Diodes

    Hi all, new guy here!

    So, I want to retrofit some HIDs (none CANBUS tricking) (obviously!!) to my 2009 Skoda Octavia (it's a VW Golf GTI with a large boot). I can code away or cheat and use resistors bulb out CANBUS errors, but I've read on some Skoda forums that if I don't utilise some kind of reverse spike protection, then I can end up frying the Body Control Module as it's a bunch of solid state relays.

    Am I right in thinking that placing some diodes in the circuit will protect from this? If so, in what configuration would I want to mound these?

    Apologies if this has been covered elsewhere, but I seem to get on well with forum search tools!

    Thanks!!!

    I also meant to say that I'm looking at these 2 options http://www.12voltplanet.co.uk/diodes.html, any preference on what I should use? I'm using 35w HIDs from here http://www.ebay.co.uk/itm/2705917253...%3AMEBIDX%3AIT.

        Well I assume you'd need them on the wire that leads from the body module, but if both do then put them on both I guess?
