GX-CS4 $529/$477 with discount code

Not much luck with those from what I've read on here. So I went with this:

Installed it vertically on the back panel, opposite side of the power cord.

I just found one that has a couple of leads attached. I’ll just wire it to the 12v leads on the power supply because essentially the runtime of the power supply is the same as the run time for the pump plus a bit extra.
 
I got this one https://www.amazon.com/gp/product/B07PFTGS2Z/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1

I has 2 resettable timers so you can zero one out when you add more grease. You should connect the one of the leads to the high side of the coil that controls the motor's relay. There are 2 1/4" quick connects unused on the backside of PCB one is ground the other is 12v when the compressor is on. That way you only count when the compressor is on, not just when the power is on.

That's handy, but since I plan to apply grease every 5 hours, it will be easy to track with one main timer.
