Hey guys.
I was trying to program the new remote on my mums car. she has a mongoose MRC200 which the remote has been replaced by a M20 remote.
the instructions are easy enough to follow however i have taken the kick panel off the car and cannot find the programming button of the alarm.
there is a small black line but it has been taped off and it goes nowhere.
I followed all the wires and cannot find any buttons.

Would any of you know how i can program the remote if i cant find the override button?

PS- Its just an immobiliser not an alarm.
