Hard start capacitor

Question

I'm sitting on top of my TT, have a new SPP6E capacitor ready to install, I open my capacitor cover and there is only one capacitor. I know some electronics, so I am assuming that this one capacitor is the run and start capacitor all in one unit. It has 3 white wires on one terminal, 1 red on another and 1 brown on the other. I know the brown goes to the fan...
Can I just add in my new capacitor? One goes to red the other to white. I don't see why I can't, but just wanted to see if anyone else has seen this setup and added a hard start capacitor to theirs.
It's a Dometic AC.

Thanks,
Waylon

You just piggy back the SPP6 (no E according to Suppco) to the existing capacitor.See comment #117 from Jim Berry in the above mentioned thread.SPP6

I did as Bob describes.

For some reason my post didn't post earlier.
It didn't work, I swapped the wires like one of the commenters in that site suggested, that didn't work either. I just saw this about not using the "E" so I'm about to go back out there and remove the capacitor and swap it out for a non E one.

I swapped out the SP66E for the non E. it's taller than the E, so I had to break off the tab on top and it fit perfect beside my other capacitor in the box. I didn't get a chance to try it out with my generator, but it sounded better when it kicked on while plugged into the pedestal.
