I used some flat metal strips , could use a thin screwdriver failing that I guess. Boost hose can just run under the dash up behind the stereo and into the back of it I assume. I have defi's so only had to run a thin cable to the back but it went fine so assume boost hose will too
i didn't block mine off, just never aim the heaters at my face/dials. I used 2 very small screwdrivers to get mine out (my have been jewelers iirc) then removed the clips before i put them back in. They sit secure now but come out with 1 screwdriver and a bit of jiggling
Not good buddy! Should put some insulating or mask tape around the tools to stop it damaging the dash. I used a really thin electrical screwdriver but was a pain to do and defo would use something different if I had to do it again.
