What fans have you fitted ... single speed, dual speed, just the factory fitted ones ???

Do you really want them both on - when you start the engine ??? ...

... or do you want then to have staggered startup times - which are temperature controlled.

There is a bunch of electric fan writeups with all manner of control setups ... that may be useful to you.


... but to offer any tips ... we do sorta need to know an idea of want you want to achieve.

i put one fan in one relay and the other in a 2 relay all i need is to know wish wire of the jeep i put it to so they trun on wen i star the jeep i want both of them on at all times i am tired of the over heating

Easy done then ...

The trigger wire to the relays ... just needs to come from an - ign on - source.

Some one with the same year model should be able to suggest a handy spot to tap into.

Just be aware you will be placing extra load on the battery ... at the same time you need starting volts ... So it might be worthwhile adding some timer relays on the trigger wire .... to delay the fan operation - until after the engine has started.

Hella has an adj timed relay that might be useful if you decided to go that way ?? ...

You have a 95 like me bro.Take and pop open the hood.Look over on passenger side theres a fuse box there.OPen it and look at lid it will tell you which block fuse is to fan.Tie into it with a wire running into one of the holes in legs of fuse plug it back in and run it to positive on battery.Turn yer key to the on position where yer heater and stuff will come on and the fans should kick on then.
