Through search, I'm reading a lot of posts regarding how the aftermarket ballasts of some HID kits causing the power steering ECU to malfunction. I understand some kits come with insulated ballasts and some do not. Just to be safe, I want to mount the ballast away from the ECUs and anywhere else unsafe. My questions are:

1.) Where are these "safe" areas? What spots are you using?
2.) How far should the ballasts be away from the ECU?
3.) Where exactly is the main ECU and power steering ECU? What do they look like?

Thanks in advance.

This is one of the examples how mounting the ballast too close to the ECU can mess with the power steering.

the p/s works on 24-48 volts not 12 volt that the ballast needs so no way it can miss with the system ,but if your taping in to power that controls it yes

i have mines mounted in the inner wheel well with double sided tape. It's a tight fit so even without the tape it sits there. Prolly not the smartest place though

The thought is that the EMI/RFI interference is frying the p/s computer. Nothing to do with the volts.

am not say that ecu and rack cant go bad because we have a tsb for steering ,but the only thing would have to be is Emp and if it did happen all ecu would be out no if ands or butts. now dont trust in all dealer I get alot of work from dealer come backs because cant fine the issue and say any partsthat are after maket is the issue and most of the time its not its the tech that suck on finding the real issue

Mines next to my battery and the other by the brake system I've had no issues since 07 and I'm good.

Isn't the battery is where there are electric current/charges flowing about?

I'm even more confused now. At first it seemed as if the malfunctioning power steering ECU was attributed to this and now it's just a guess? Seems like there's a lot more people with aftermarket HIDs without problems than there are with problems but I'd still like to play it safe and mount them in a safe spot. So where are these "safe" spots? Any other suggestions? Those videos of the shaking steering wheel is pretty scary.

If you want to be safe and don't mind the trouble, just mount it on the front reinforcement bar. Had it there for 4 years now and never had a problem.

Just out of interest where is the power steering ecu?
