OK guys, I know this sounds stupid but I just need to make sure I'm doing this right. First time using a crimping set so bare with me lol! Do I make a cut in the reverse live then on top end of butt connector insert the sensors red live alongside one end of reverse live then on other end of butt connector insert the remaining part reverse live? So in summary you have two wires (1 pt of reverse live and red live from sensors) going into butt connector on one side and going out on the other side just one wire (2nd half of reverse live). Once again sorry for sounding dumb but I'm used to just cutting and soldering but my iron is broke so gonna try crimping the electrics now on. (If all goes well lol!)
Yeah that's right. You can get small triangular connectors that take 3 inputs, so if you have one of those in your set you could use that instead.
Otherwise, yes, cut the live to the reverse light, put one bit of the cut wire in one end, and put the other bit + the parking sensor live wire into the other.
