i would say it is and isnt a good idea because you have to splice into the wires going into your ecu. which could void your warrenty on something lol but to each their own. and it should be to hard just splicing wires together just be careful and read the directions very well and you should be good to go. just dont use butt connectors you will want to solder the wires and heat shrink them. any performance could have it done fairly quick.
