I've had fitted to my 2010 Prius some nice Revier DRLs and just used an aftermarket relay so turns on and off automatically. However just bought this so i can turn them on and off as/when i want too. http://bit.ly/105qjYO Just pulled out the panel next to the steering wheel where the electric mirror switch is and I can see a few cables in behind, 1 looks very similar to the one I have in this pack! Also when I look in the fuse box in the engine bay there is a relay that has DRL written on it! Anyone know if this is the OEM cabling? Would be good I could somehow use the original OEM relay instead of my aftermarket.
