        Did Just that not long after I got My 1st H2OBoxer back in ’83 & also did it to My ’90 not long after I got it in ’06,,, Mine are connected to the High Speed circuit since My aim was to be able to switch the fan on high as I would be approaching a significant climb while loaded with a bunch of boating & camping gear & with a Canoe or 2 on the roof rack & a Raft trailer with a Raft or 2 hitched to the rear, in order to keep the Cooling System from even thinking a little bit about heading for high temps,,, It has worked out great for many years & I have also considered on numerous occasions about replacing the Single Throw switch with a Double Throw switch to provide manual control of the Low Speed as well ~
Using “T-Tap” on the wires right @ the Radiator Sensor/Switch makes for a very simple way to do the mod’ ~ If You are not familiar with “T-Tap” just Google it ~
