How to implementing BAL on a RepRapPro Tricolor?

Hello.
I'm needing some help.
I'm trying to implementing BAL on my RepRapPro Tricolor, because my bed is curved and I don't have a good alignment. So I was thinking in implementing BAL to get best bed alignment. But My RepRapPro Tricolor has own configuration of Marlin and I don't know how to proceed.
I was looking for Marlin implementation on github and Marlin of RepRapPro Tricolor and has a lot of differences.
Can anyone tell me if could configure BAL on RepRapPro Mono or Tricolor Mendel?
Thank you.

I assume you are talking of auto leveling...yes, fairly simple to setup but you will need some form of switch and/or servo setup for it.

You're right, bed auto leveling.
But in my case it isn't easy because the implementation of marlin is diferente of original marlin release on github. The Marlin was adapted for my printer model, RepRapPro Tricolor, and in configuration.h file doesn't have the implementation of bed auto leveling.
And I was looking for a solution to servo adapt and I found some solution where isn't need to use servo motor. Look this: [www.thingiverse.com] and this [www.thingiverse.com]
I talked with Alex Borro, a active member of this forum, and he said me I can use z_min_endstop of my printer to connect endstop.
But the big problem is the Marlin's version for my printer. I think dangerous changing something because I don't understand so much, and I'm afraid to destroy my printer

just use different Marlin Firmware and setup.I have reprappro mono and use this firmware

Thank you premek.
The RepRapPro support said me I should specify the thermistor but I don't know where I should specify, Is in configuration.h file?
Thank you.

look for this in configuration.h.i included config what i use with my printer with I2C lcd display.You will be need adjust same setting to yours spec

//
//--NORMAL IS 4.7kohm PULLUP!-- 1kohm pullup can be used on hotend sensor, using correct resistor and table
//
//// Temperature sensor settings:
// -2 is thermocouple with MAX6675 (only for sensor 0)
// -1 is thermocouple with AD595
// 0 is not used
// 1 is 100k thermistor - best choice for EPCOS 100k (4.7k pullup)
// 2 is 200k thermistor - ATC Semitec 204GT-2 (4.7k pullup)
// 3 is mendel-parts thermistor (4.7k pullup)
// 4 is 10k thermistor !! do not use it for a hotend. It gives bad resolution at high temp. !!
// 5 is 100K thermistor - ATC Semitec 104GT-2 (Used in ParCan) (4.7k pullup)
// 6 is 100k EPCOS - Not as accurate as table 1 (created using a fluke thermocouple) (4.7k pullup)
// 7 is 100k Honeywell thermistor 135-104LAG-J01 (4.7k pullup)
// 71 is 100k Honeywell thermistor 135-104LAF-J01 (4.7k pullup)
// 8 is 100k 0603 SMD Vishay NTCS0603E3104FXT (4.7k pullup)
// 9 is 100k GE Sensing AL03006-58.2K-97-G1 (4.7k pullup)
// 10 is 100k RS thermistor 198-961 (4.7k pullup)
// 60 is 100k Maker's Tool Works Kapton Bed Thermister
//
// 1k ohm pullup tables - This is not normal, you would have to have changed out your 4.7k for 1k
// (but gives greater accuracy and more stable PID)
// 51 is 100k thermistor - EPCOS (1k pullup)
// 52 is 200k thermistor - ATC Semitec 204GT-2 (1k pullup)
// 55 is 100k thermistor - ATC Semitec 104GT-2 (Used in ParCan) (1k pullup)
