I recently purchased a set of PIAA driving lights. I intend to mount them in the oval cutouts in the lower front bumper of my 99 C280. The kit is complete with harness, relay fused lamps, etc. However, as we know the battery is mounted in the trunk and the harness is ain't long enough for that. I would like them to come on with the foglight position on the light switch, any suggestion on how I can find this wire or any better ideas for mounting them.
