So I'm gonna preface this with I originally tried to buy what I needed from Morimoto. They have good products but just awful customer service and overall knowledge. Long story short I accidentally ordered a 9004 kit instead of a 9003 kit, called them and set up an exchange for the bulbs and harness, then they just processed a return instead. Now they are trying to tell me that their can-bus style will not work on my 94 LS because it will cause "unnecessary strain" on the electrical system. I have been running their can-bus style system on my SC300 with zero issues. Furthermore I don't want to wire in that bs relay harness, which is what they are saying I need rather than can bus style. Its a pain in the @** and not plug and play. At my shop we've installed these on customers cars and had nothing but issues with stuff not working and having to jump through hoops to get the right stuff or not faulty stuff (hence the frustration with their awful customer service).

Questions:
Anyone know of this unnecessary strain on the electrical system that they speak of?
Can anyone recommend another company that has quality HID kits or even LED kits for these cars?
