Please help me wire my fan so it comes on with the key in the "on" position. Its a 88 305 TBI

 

all i did with my elec. fans on my 87 Formula was move my ground wire from the thermostat relay to a solid ground on the car it works fine on an off with the switch.

 

when you say "switch", do you mean key?

 

yes when the key is on the fan comes on an when it off so is fan
the car runs alot cooler too.

 

Thanks man, but does your Formula work like my 88 TBI? Yours might run off the ECM somehow, mine dont.

Your probubly right, but I really want to be sure before I go and yank some wires out of my relay.....

Also what did you use for a good ground??

 

hey fella..

I just rewired my fan so it comes on when the key turns... Here is what I did. First clip the wires by the fan. I have an 88tbi.. so it should have the exact same setup. We put the ground to the wall just behind the battery. There was already something on the same screw..I think next to some kind of black box fusething. The power wire we ran to the fuse box. What fuse I would have to check over the weekend because I dont have it here, Im at school. Once I do, Ill let you know. But it takes like 20 min. It might have been the radio fuse now that I think about it.

 

yes that will work too.but my Formula had power at all times the relay when it gets hot opens an completes the ground circuit.so all you need to do is clip the ground wire an run it to the bolt like he did

hope this helps

i got a few f-bodys an have owned a lot of others its one of the first things i do..

 

Thanks a lot guys. You have been a lot of help.

JRupert99-please get back with me some how on what fuse you used!

THANKS A LOT!

 

Ill check tommorrow and post after I get home from work. I should be home no later than 9pm... But I am almost positive we went through the radio. Just to make sure Ill check tommorrow

 

Well guys, I tried the first option that 87 Formula gave me and it worked! So thanks guys.
