Im not going to half ass my car, when I can afford it I will buy a tuck harness, I do it right or not at all, Ive been working on this car for 3 years, Could you imagine how much money I would have in it if I half assed everything and then went back and done it the right way...Plus when you half ass stuff, things go wrong, what happens if your on a long road trip, and one of those wires grounds out and fries an ecu?? or even worse, catch the car on fire... I think it should be done right and worry free, thats just my $.02
