new addition to my cooling system today

i have the pretty much stock system, other than a high-flow pump and lower temp fan switch, but today i put two indicator lamps in my dash so i can "see" when the fan(s) come on (dual fans). nothing special, but thought it'd be an easy way to monitor them, especially with a/c on and driving in traffic.

Nice shoe/slipper.

The lights are a good idea too. How'd you wire them in?

The following link, under, "Other Issues," will provide an idea.

By the way, I still have some of "Fans On" transparencies if anyone is interested.

pos wire for both to a "key on" circuit, in this case, the one that goes to the ecm. the negative wires were spliced in near each relay, to complete the circuit. figured i'd do it that way since then i'd at least know i had a completed circuit up to that point. so when each fan circuit is grounded to complete its circuit, the light(s) come on.
