How to swap pinouts in Marlin with Ramps 1.4

If I wanted to swap D9 with D8 what would I change in Marlin using a Ramps 1.4 board?

pins_Ramps.h

#if ENABLED( IS_RAMPS_EFB ) // Hotend, Fan, Bed

#define HEATER_BED_PIN RAMPS_D8_PIN
#elif ENABLED( IS_RAMPS_EEF ) // Hotend, Hotend, Fan

#define FAN1_PIN RAMPS_D8_PIN
#elif ENABLED( IS_RAMPS_SF ) // Spindle, Fan
#define FAN_PIN RAMPS_D8_PIN
#else // Non-specific are "EFB" (i.e., "EFBF" or "EFBE")
#define FAN_PIN RAMPS_D9_PIN
#define HEATER_BED_PIN RAMPS_D8_PIN
#if HOTENDS == 1
#define FAN1_PIN MOSFET_D_PIN
#else
#define HEATER_1_PIN MOSFET_D_PIN
#endif
#endif

So I just change the lines with D8 and D9 and swap them? Which version of Marlin is that as 1.1 does not have those lines.

Marlin is so much easier to follow than Grbl but sure is slower too. In Grbl (which is what I really want to change) they stupidly have D10 has flood coolant and D9 as Coolant mist with the fan controller on D8. They did this, so they say, because Ramps has a heatsink on the fet for D8 but I call BS because there has never been a heatsink on any I have seen.

Anyway I thank you and I hope I can figure this out in Marlin so I can use the information where I need it since the author of Grbl-Mega stays quiet when asked the same question.

The heatsink was in the the original design, but all the cheap china clones omitted it to save a few cents

On my Ramps there is no way a heatsink would fit and it got so hot it melted into the plastic that holds the wires. That one was made by Sainsmart and it burned up and shorted so the next one I purchased was from eBay and I swapped over to IRF mosfets (all three though only one really needed it) and after a 24h print not even the heated bed's fet was warm to the touch but the old one with the spec fets blistered me it was so hot. I always figured that if your design calls for a heat sink you are pushing it too much so find a better part and only use a heatsink as a last step if nothingi s out there. I am not sure why they chose the horrible fets they did when it didn't cost me any more for quality ones that never even get warm let alone fire potential hot.
