I pulled the fog lite cut-out out and saw a wire harness with a yellow plug just sitting there. I assume this runs to the SAM? Is there any way I can use that harness/plug without having to go to MB to activate it. I am installing an 8 row led lite in there and haven't decided if I want them on for day and nite or just when the head lites are on.

please advise on what you think i should do and how to activate them



thank you for your help

I ran my own wiring down there. There's a slot on the SAM that only is switched on with the ignition. You can wire up some lights to it, then run a switch to a blank space on the button bank to make a factory-like setup.

I think there's an Evilution article on it somewhere...

But for me, I use my fog lights as a DRL setup that's not unlike an Acura MDX, so they're wired directly to that open slot on the SAM. They only come on when the ignition is on and they're on for the duration that the ignition is on.

The answer to your question as you asked it is.......No.
If you use the existing wiring harness, you will need MB to activate it.

You asked the same thing in your other thread ...http://www.smartcarofamerica.com/forums/f377/driving-lite-plug-141753/

Terry,
Just in case you maybe contemplating splicing or cutting on the wiring harness going to the "sam" I'll refer you to niteshooters advice in your post March of this year.

My take on this is that you might be asking for trouble. Problem with some aftermarket upgrades such as what you are suggesting may put too much strain on your existing wiring and SAM and the result would be melted contacts and damaged wiring. Same reason installing halogen bulbs in old cars (70's and 80's) could be a good or bad thing as the wiring was not up to snuff and it was mandatory to use a relay or risk melting the existing switches and wires. My understanding is that the relays are on the SAM so if you fry something it isn't going to be cheap...........

Good advice there Jo e Lefors! :)

Yeah, if you're adding accessories to the car, use the open ports on the SAM (usually they're for features your car either didn't come with or just weren't available on the US models) with proper gauge wire, proper fuse, and grounded to the grounding posts located in various places in the car.

Done well, it'll last you effectively the life of the car. :D

Check around for an independent shop which specializes in european cars. I found one locally with a Mercedes Star system which was able to activate my fogs for $30. Saved me the long drive to the smart dealership and lots of $$$.
