Question Connecting bi-xenon HID to Fuse Box

I received a 9004 bi-xenon kit from xenonlink. This requires a connection to the battery (which is in the trunk as we all know). I have read the HID posts and have read various others' suggestions of wiring this HID connection into the fusebox and splicing this to one of those wires for power.

I can see how to get the HID kit wire requiring power into the fusebox via empty grommets. Once I am there where should I splice this connection to connect safely to power? I am afraid of frying something and do not want to cause electrical problems.

Thanks,

Remember to disconnect the negative side of the battery before working inside the fuse-box.

If the HID kit comes with it's own fuse/es, splice into the fat red wire inside the fuse-box. If there are no fuses with the HID kit then it's best to find the headlamp fuse and connect to the fused side of the wiring.


EDIT: You will also probably want to remove the 'lamp out' warning light on the instrument cluster as this will illuminate when you switch on the headlamps.
If yours is a LHD car there's no need to remove the cluster, just drop the panel below (four screws) and twist out the warning light and remove the bulb.

No trees were harmed creating this message, however some electrons were very inconvenienced.

Benzmanbandit was going to send some pics of his xenonlink bi-xenon install---but he has been absent from the forum lately so I am hoping Redliner or someone can provide me some direction to get started.

I have a 9004 bi-xenon kit from xenonlink which requires a connection to the battery (which is in the trunk as we all know). My kit has a fuse to prevent the bulb out warning light.----- I have read the HID posts and various others' suggestions of wiring this HID connection into the fusebox and splicing this to one of those wires for power.

----when I remove the fusebox cover, I do not see any obvious "fat red wire". Do I need to remove the fusebox by unscrewing the screws to access this wire?

If anyone has any pictures or DIY directions etc I would much appreciate this.

Thanks....can't wait to see better at night!

You may want to take it from the source.
In the module compartment.(Right engine side, next to the hinge.)

The battery cable comes from the battery direct to that location.
In there it splits to the fuse box, alternator, etc.

Start at the connector with a fuse and way you go.
Take as many amps as your heart desires.

Regards.

aam, (thanks for your suggestion)

I am not certain which is the module compartment---is this the large rectangular box connected to and immediately rearward from the fusebox?

If this is the module compartment, do I just pull out the fuse panel out of the way to access that area?
To safely lift the fuse panel from the box, do I need to remove anything else other than the 4 screws (two at front of box and 2 at the windshield side of the fusebox?
Is there enough slack to pull the fuse panel out of the box without worrying about dislodging something?

Sorry if I am acting stupid questions. I definitely do not want to screw something up by carelessness or ignorance and I am not finding any information or procedure on how to do this.

About four feet from the fuse box to the right.

There was not masses of slack on mine but enough to lift and gain room to splice into a +feed with a little care. My kit had built in fuses so I just picked up from the fattest live I could access easily.

aam,

Is this the large lead you are talking about (identified by clamp at top in image 1a) and 1b?

Is it safe to splice this further toward the front at spot pointed by screwdriver (image 2)?

Thanks,
Roger

No, in your first picture where your clamp is move to the cars left about 6" where this hole/opening in your picture look doooown on the floor you will see the maybe red cable
it goers in a plastic box remove the cover and it is there.

Remember our cars run for 12 years, not all the connectors are located exactly
on the same spot, but you are getting there.

It is like making hmmm,,,, during the day it is easier, at night is a little harder to locate things, but if you follow the trail.......

Love pictures send more not close ups I like to see more of the field.

Regards.
