i mounted one on the pass side to an empty bolt hole that i had since i remove dthe stock air intake pieces for my HKS filter.
the other one i think i stuck betweenthe battery and fuse box cover with 3M body tape.

Sorta stealing the topic, but I'm about to get an HID kit for my '92.

cheesey said he installed the JDM lights, and thus has the H4 bulbs, I assume? I'd like to get a kit that does high/low beam since I hit unlit roads often. Anyone know if I'll still need to do extra wiring if I get a 9004 HID kit for mine, or would it actually be plug and play?

yours should be plug and play if you keep the usdm lights.

pt your own fuse in! its easy... the fusebox is on teh drivers side front fender. just pop the hood and look for a rectangular black box with 2 phillips screws on top. under the cover is a label telling you fuse locations.

you have to make your own circuit or forget about high beams. i chose to forgo the high beams since they didn't really seem necessary anymore.
not true..

wow this thread is old.

I'm planning to purchase an hid kit from ddmtuning.com (a lot of bimmer guys buy from them). It'll be a true bi-xenon. Will i need a relay harness so that when i turn my high beams on it won't blow the fuses? Should i get the relay harness anyways so that i don't melt my factory harness?

What does the word "need" mean? A relay is used to ensure that your add-on "whatever" (an HID kit in this case) gets full power by correcting it directly to the battery or a terminal on the underhood fuse box. A wire from the relay to the existing headlight harness is used to trigger the accessory (HID kit in this case) to turn on.

Even the Hella Supertone horns I had on my previous LS sounded wimpy unless I powered them from the battery with a relay and connected a wire from the relay to the existing horn wire to trigger the horns to sound when I pressed the center pad of the steering wheel.

May sound complicated but it's not.
