Review on Spal 185FH Cooling Harness Relay by Anthony Daniels

Great little relay, be sure to get a 3/8" NPT thermostat housing adapter to lower radiator hose or you have no choice but to install it with a one- /off switch, the 1/2 inch adapter is useless as they are even harder to find. And good luck finding a 3/8" NPT adapter on ebay, not sure why they decided to make it so much larger than the standard 1/8" NPT, but besides that it works very well with I still want to buy a 3/8" NPT adapter so I can't comment on how well it works. But other than that the relay does the job and the cables are long and good quality.
