This set up is on my son’s 92 745. I already have the wire through the firewall to the float switch so I will just use the switch for the ground to the coil. Whenever I need a wire through the firewall I push it through the rubber grommet that accommodates the cruise control vacuum hose. I have always installed the switches on the bottom of the reservoirs. While I realize fuse taps are not the best way to get 12v I always use the protected side of the fuse for the tap and haven’t had any problems.

I maintain four 7/9 series cars (including two turbos) and they all have black reservoir caps. I haven’t had any problems with them running hot. I think the black caps help guard against stressing the cooling systems in our “old” cars.
