    Rated 2 out of 5 by from Just crap quality and control First off it had a hole in the bag with all the parts. So it was all over the box. Come to find out I was missing one bolt and a oring for Modulator plug. It installs easy even with the crap directions. The one long bolt that holds the detent is to short. Just use a stock one. I had to find a short one but I have a good selection of bolts so not a problem. The 12 point bolts were a 8 mm. Also the wires were on the top of the solenoid so they wouldn’t reach the plug in the case. So I had to spin it 180. The little nuts are 1/4. With red locktite. Also the Modulator plug is to short but luckily I had an aftermarket one with the oring so it worked perfectly. You also need a eye let electrical connector for the ground with a 1/4 hole. It might come with it but like I said before my bag was all over.
