matts87glsedan Posted April 27, 2008 Share Posted April 27, 2008 i had some trouble with my thermoswitch last year, and wired my cooling fan to a switch on my dash. Its not a perfect setup because its 16 guage wire run from a tap behind my fuse box (on the fan wire), to a dash switch, to the fan. the fan is grounded at the thermostat housing. the poles on the switch get hot, like hot enough to mildly burn a finger on. I want to use my existing wiring to power a relay. The fan is listed in the FSM as 120 watts (so 10 amps right?). The only relays i have right now are the round underdash ones (i think for headlights and such) listed at 20 amps. Is there any reason i shouldnt use this relay? it should handle 10 amps no problem? my existing 16 gauge wire should be fine for the low power side, what guage should i use for the high power side? I used daerons write up to wire two 100w spots with a relay, so i've done this once before, i am just paranoid about those round relays for some reason. thanks , and if you see any other problems with my set up, please let me know. ( i dont want to burn up my car!) Quote Link to comment Share on other sites More sharing options...
