It helps but would need to see the coolant hose side of how it is T off and the orange wires connecting back to the power box. Also since it is off can your friend see if they csn get the part # of the inverter and cables needed too? Thanks

Actually the 240v inverter part # is NL3Z-14G649-C which is alot cheaper and doesn't need a core return.

Lightning is different. You install it under the bed near the spare tires. You don't remove the 2.4kw system you are adding 7.2kw to it.
We just need someone with the 7.2kw pro power to remove the bed to see how the connation goes and how they Tee off the hoses.
