I'm no expert either but even I know not to solder anything on a boat
Use heat shrink butt connectors, properly crimped and sealed so the connections are solid and waterproof, especially important on a water pump
the shakes and vibrates when in use.
You can experiment
with connecting your indictor light to any of the connections. Your goal, if you want to continue using it, is that it lights up when the pump
turns on and goes off when the pump
stops, it's not rocket science and won't hurt anything to test using it. I would start with one of the pressure switch connections, but I'm an amateur so don't listen to me.
You don't really need and indicator light of course, BUT if your pump is hard to hear from the living spaces the indicator light gives you a heads up that it's working, and if it doesn't go off it gives you a heads up that your tank might be dry, system needs bleeding, or some other problem.

But yes. The new one has two red wires going to the top pump. But look at the old one. The old one has the two red from the bottom going to the delay:
And, this is the new one:
Johnson Pumps 10-13395-103 Aqua Jet WPS 3.5 Water
Pressure Pump, 12V
It's almost identical except the bottom cables
(one goes to the pump on top (or is it motor
on top) and one goes to the relay).
