This is a really nooby question but I need to get this clear in my head. Mum wants parking sensors for her Civic (DIY opportunity). I've taken the bumper off etc so only the wiring left. The way I see things - I have to crimp the black wire to the circular terminal and put it on the ground bolt. For the red wire I have to connect it to the reversing wire (green). To do that I have three ideas: - Soldering (least preferred) - Scotchlock (do I cut the green wire in the middle and thread both ends either side into the scotchlock connector along with the red wire on one side?) - Heatshrink (can I cut the green wire, strip both ends, twist the red cable into the end coming from the engine and heatshrink it with the other end going to the reversing light?) I've basically asked two questions, anyway thanks for reading, I know its a really stupid question but I want to make sure I have got it right in my head.
