Where do I connect on a 90 Chevy Lumina w/ 3.1 V6 to monitor for primary cooling fan enable signal from ECM?

I have already designed a LED circuit, I simply need to know where I should look for the signal from the ECM to the primary cooling fan's relay so that I can connect there and then see, via LED, when the ECM enables the cooling fan relay.
