auto bed leveling help advice

want to do auto bed leveling on my custom prusa i3

i have a 9g servo from my rc plane and a spare mechanical endstop
would need to print mounts but not too much of a problem

where do i wire servo to ramps 1.4 and where do i wire endstop too as most vieos just show mounting endstop
theres a lot of videos out there that make it confusing
need to know what to put in marlin too

what good reliable guides are there

Hi,

The servo is plugged on the D11 and under pins.
The enstop is plugged in the Zmin input.
Caution, if you use a microswitch without PCB
you need to uncomment //#define ENDSTOPPULLUP_ZMIN

For most of the autobed enabling folow these steps :

Then just enable servos on Marlin.
