I want to rig up a switch that will automatically turn on the fan, no matter the temp or if i have the AC on... it is a 91 RS with stock electrical, so the fan is electric with a thermostat and all that... just wondering where to splice the switch in. diagrams appreciated

 

I put mine in on the ground side of the relay, it works like a charm. i can turn it on manualy, or if the switch is off, the normal fan switch still works.

 

which relay, where is it located? im new to 3rdgen electrical

 

it is on the cowl area, drivers side. there are two of them there. one is the fan, one is the fuel pump. i forget which is which, but i think the one closest to the fender is the fan relay.

 

ok, ill try that, but anyone else who could diagram me up would be cool, i have the chiltons manual, but its confusing as all heck

 

i scotch locked mine directly to the fan temp sensor and it works perfect

 

the thing is, i dont think i have a fan temp sensor, my fan doesnt come on unless the a/c is on, no matter how hot it gets... hence the reason im puttin in this switch i dont have enough knowlege to know what the fan temp sensor looks like, or what the wire going to it looks like... all i know is that its on the passenger side of the engine... and i havent found it on mine yet..
