I am 90 % done with my wiring for my Hella Driving Lights. All I have left is this blue wire that I assume is meant for connection to a switched power sourse so that the lights do not stay on when i turn the engine off. I am planning on doing the add a fuse method so that I do not tap into wiring for this switched wire. Will this work? Can anyone confirm that I am correct that this bear blue wire is for connection to switched power?

Thanks
Carl

 

Carl,

It sounds like you're using a wiring harness built by Hella. If so, the blue wire indeed goes to switched power supply. It is intended to be connected to the high beam of your lights (it is the law in some states). The easiest way to determine which wire is which is remove the power connector to one of your headlights and test each light colored wire (brown is ground) for power. I found using a test light was great for this since I was working alone and couldn’t see the reads on my volt meter. The wire that has power when the high beams are turned on is the wire you want to connect the blue wire to.

Hope this helps!

I hope Carl didn't wait for someone to answer his question before proceeding... since he posted this in October of 2005....

Better late than never.

 

At least WX04 is willing to help!

Cheers!!

 

Yep & that's a good thing.

 

Thanks anyway. It was easier than I thought. I wanted to be able to control when to put them on. I did not wire them up with the high beams.

 

Arly where did you run the wires through the firewall? I've got access to a grommet on the drivers side with what looks like a "cut off if you want to go through here nipple" on it but can't tell where it comes out on the inside.

got it

I referred to the oem light installation instructions where they clearly state "just punch a hole in the big grommet with a sharp metal object". I may take more care than is indicated in those instructions.

 

[SIZE=3][FONT=Times New Roman]I went through the large grommet above the steering wheel which is located behind the master brake cylinder booster . I found if I used the ground wire from a #12 residential wire I could better control where I placed my hole in the grommet. Since access to the grommet by hand is difficult I taped the wiring harness to the #12 wire ground wire and used it to push the harness through the grommet. Then I climbed inside the car and pulled the harness all the way through. After I was satisfied with the positioning of the harness I pulled the harness back through the grommet about an inch and covered it with silicone sealant (RTV). I then worked the harness back and forth through the grommet in order to seal the hole with the silicone. After the silicone dried I covered the grommet and harness with speed tape (aluminum duct tape). [/FONT][/SIZE]

Pretty much what I did. I took 14 gauge copper solid wire cut on an angle. Poked it through the grommet, went inside and pulled it clear of any potential shorts. Went back out taped the 4 wires from the harness going inside to it and push/pulled them through.

I only covered the hole with black duct tape to make a watershed. (MINI had done the same a little higher on another grommet from the factory -checked both cars)
