I've done the research, just a little unsure about connections. I have a 1990, I attached a pic, of what I understand is the correct way to wire. Not 100% sure, which relay wires to tap, is it the two blue wires? One relay has a blue/white and the other appears to have a blue/black. And then I just run a third wire as a ground?
I've read it's okay to run both fans. And, I've also read run only one fan manually.
Thoughts?
Many Thanks!!

I've done this on my 94, (should be no different on a 90). My car is still in storage, so I can't see the wire color, but believe you are correct on the blue wires. I used a wireless remove to activate each fan separately, I would turn on one and if he didn't cool enough, then I would turn on the 2nd one. Using the wireless remote I didn't have to run any wires into the car, all wires are under the hood. I think I have an extra wireless remote, (if I can find it) I tried looking at Ebay to see it but history only goes to 2018. It was only like $12. Found a link to one like what I used.

Need help with running manual fan switch, please?
