i dont know why you wouldnt pull off the master cylinder it was tight enough as it was with it out of the way. i bought the line lock solenoid and a set of lines and fittings from jegs and it cost a third of what everyone else wanted for some pre bent lines. all you really need is a big socket and line bender. I have to thank you for your awesome write up i followed it for the majority of the install. i wired a master switch in my center console then wired a relay to my cruise control off button. it works great and is all hidden,
