Firebird starter and door lock problems

Hi 

I have two questions to see if you could help me

My door loks is always locking everytime I press the foot brek parked or while driving I know they lock when I first start driving and unlock when I shutoff the car but they shouldn't lock everytime when i press the brek while driving

second when I remote start the car it trys to crank again after it's running

i connected the tach wire to the wht wire from the passenger side of the harness I tested the wire and the signal is 0V to 1.3V when adle and when I rev the car goes up so I think I have the right wire if I do have the right wire then what's the problem do I need to learn the tach wire to the starter unit and if so how do  I do it  because the alarm manual doesn't say

also I tried to desable the auto door locks lockout and the interior lights delay and it didn't work, is it because I have an aftermarket MP3 player do I need to put back the factory radio casset  because of the antithef module

my car is 1996 Firebird convertable 3.8L Auto

alarm is al838s

Im not using a relay for the trunk release it works without spliced on BLK/WHT after factory relay

I used the door triger with door locks to waikup the RAP

I maid a antithef bypass module and a starter killer

Ok I have fixed the starter problem i endup not using the tach wire, I think the signal wasn't very strong, I used the alternator wire and it works good.

now I just need help with the door locks

come on guys I'm sure there is an intelegent person out there that would give me an idea why this happens

thanks for your help

Thanks Draasch

that's how I wired the door locks right from the beginning for them work properly, the door locks are working fun the only problem is the that everytime I press the brek I hear the locks trying to lock when I'm driving (here is the story I start the car switch to gear the doors lock like it should then after that everytime I press the brek it tries to lock again even when the car parked and running doesn't make a diference hom many times I press the brek it trie to lock everytime "like this I press the brek lock press the brek lock does that old the time the brek is pressed"
