Review on HELLA 148541001 Rallye Wiring Harness by Quinton Dawon

When you have no idea what you're doing and need to figure out how to install new fixtures, this is a great all-in-one solution. Two very nice end caps that fit snugly into the tail light housing are supplied with a relay and fuse switch. The instructions are simple but mostly based on graphics. With the confidence that comes from this little tweak, I wire the extra headlights I bought for my truck myself. I had to extend the switch wiring to get where I wanted, but it was easy enough. Highly recommended for a serious lighting installation decision.
