How wire daytime running lights on 2007 M35?

[bernrich]

I'd like to install aftermarket (or Infiniti?) daytime running lights (DRL) on my 2007 M35. I understand the DRL's positive wires should be connected to the ignition circuit so the lights are always on when the engine is running; correct? If correct, how/where do I find the ignition circuit? Is it easy and safe to splice-in the positive DRL wires to the ignition circuit without causing an electrical or computer problem?

If some other method or connections should be made, please explain how the wiring should be done. For example, while it seems impractical, if the circuit to be used is in the fuse box (is it the fuse box in the engine compartment or the fuse box in the passenger compartment?), how do I identify the ignition circuit fuse; and how could I safely connect the positive DRL wires to the ignition circuit fuse without causing an electrical or computer problem?

out of curiosity... why do you want DRLs? it seems 90% of people want to rid of them... and you want to add them? just curious... i hate electrics and am no help in answering your question

I'd rather be seen than not seen when it's not dark enough for the auto headlights to come on; and I'd rather not have to remember to turn on any lights myself. My Lexus and Tahoe both have DRLs; I like them.

While I don't have the answer to your particular question, I highly advise that you do NOT simply wire it into the fuse box on an ignition circuit. Adding another circuit in parallel will drop resistances and cause increased amperage, and possibly fire.

If I could splice pretty low amperage LED daytime running light positive wires in to the ignition wiring (assuming I could find the ignition wiring), do you think the dropped resistances and increased amperage would cause a problem such as a fire risk? Or to eliminate the risk would I likely need a heavier fuse for the ignition circuit? How would I determine how large a heavier fuse?

If I'm encouraged to proceed, how do I find/identify the ignition wiring and the ignition circuit fuse?

if you can find a wiring diagram it can't be hard

Use a relay. Probably your safest bet.

Turn them on when you start the car, turn them off when you get out?


The pursuit of complication for its own sake never ceases to puzzle me.
