8th Generation Honda Civic Forum - View Single Post - DIY Oem Fog Lights with Parking Lights/ 06si

I haven't tried it yet, but I have an 07 Civic SI and i checked both the positive leads going into the relay and both sides have power 24/7, it seems all that would need to be done is cut the blue wire at the top of the "T" and tap it into the purple wire on the switch. Basically just bi-passing the multiplex unit.

If anyone has the wiring schematics for the multiplex unit/fuse box we could probably figure out a way to do it from there and even get the dash light on whenever the fog lights are on, not just on low beam. Could possibly need 2 small relays to replace 1 (low or low/high beam relay) or just move the wire(s) from the head light relay to the parking light relay. Not sure until I see the schematics... I would much prefer to do it this way than cut/tap wires in the harness.
