HIDs and stock multifunction switch - SRT Forums

vegitalv12 · 07-13-2005, 10:25 PM

After reading several post about the crappy multifunction switch, I rushed to my local autoparts store to buy stuff for a stronger driving circuit. The store didnt carry Bosch or the AAMP relays. They just had an off brand 40A relay. Will this be sufficent? Also, how many HID owners out there have / have not upgraded the driving circuit yet?

Hate to break it to you but there is no such thing as a safe harness that it "plug and play". The relay, if it is a real safe harness would still need to be given a chassis ground and also a direct power input directly from the battery, fused ofcourse. Also the ballasts themselves have to given a chassis ground to give them the proper ground they require.

Listen to him he knows what hes talking about.

So this wiring harness will make installing aftermarket HID's safer?

E-BlueRocket · 07-15-2005, 06:32 PM

it will make it so your stock wires dont have all that current draw on them and burn em out, the harness uses relays to distribte power safely

**haknslash** · 07-15-2005, 07:13 PM

Yeah exactly what he said. Think of it as this. Basically all this harness will be doing is by-passing your existing stock wiring making this harness your safeguard from it causing possible expensive damages to your MFS or stock wiring.

^ How much is it and do you have a picture?

Here are pics from the testing phase. It is now installed. I will snap some shots of the installation tomorrow.

I went an extra step and soldered all the crimp connections. I didnt want to take a chance on one of those connections coming undone.

And another

I just hooked everything up to the stock stuff (PnP) and use the stock switch and all and haven't had any problems.

Well you should know whats happening behind the scenes. Your HID is working ok now, but in the future you may have problems...after many cycles of high inrush current have played havok with the inadequate contacts in you MFS.
