1997 WOT relay 5 prong female fan prong missing

Hey I have an issue with my AC. I bypassed the low pressure switch and I still didn't have clutch power. So I moved to the relay. At first when I would wiggle it the relay would turn on the ac clutch. So I removed the five prong relay and the 87 female connector in the power box broke/ missing. I pulled the power box off and can't find a wire or clip or anything that is going to the 87 position. I don't know if there is suppose to be a wire going there or a jumper bar. But if you all have any expertise in this area please help. I was able to bypass the relay from 30 to 87a and the clutch kicked on an all that but I would like to have the relay in. Bc I think the 87 controls the fan speed. but anyway Thanks. Ive attached some pics. I plan on hitting the junk yard in a couple days and ripping on apart out there but in the mean time id like to figure it out. thanks

That's correct, normally when relay is activated it uses pin 87,

But in this case pin 87a is always activated so the A/C works, when going to WOT pin 87a is de-activated shutting off the A/C, should be no wire to pin 87 in this case

So make sure your replacement relay has an 87a and not 2 87's
