Black widow alarm on 1989 ford F-150

I have installed the Black widow 4150 on my 1989 ford f-150 and i cant get it to work completely right.  First of all the LED is not bright. I think that there might be a problem with the ground.  I know that I hae wired all the other wires the the approiate wires.  On the install directions it says to connect a cerain wire to the negative wire for the door trigger.  There isnt a wire to do that so would it be the same to just tie it into any ground.  I did that and it hasnt worked .  I am going to try a few different things but if any one has any comments or suggestions please let me know.

what its probably meaning is connect the green wire for a negative door trigger. if your vehicle has a negative door trigger according to the tech soft software a 89 ford f series truck has a positive door trigger so you would use the purple wire, and not the green, so the green wouldnt be used. as for the LED's black widows are notorious for having faulty leds that sometimes dont work at all. i

does anyone know about the door locks for the same system. I think that i have to have a seperate relay for them to work is that true?

I tried to put in the keyless entry feature on my 1989 ford f-150 yesterday and it didnt work.  The diagram on this website for 5-wire alternating was the one that i thought was supposed to work but all it did was blow the inline fuse on the 12volt constant feed to the relays.  I am positive that I had all the wires going to the right place according to the 5-wire diagram.  I think that this system is some sort of reversal system. First of all what type of wire configuration is my truck and how do i wire it up so that the alarm and switch will unlock my doors?

well, it sounds like you may have wired the switch and motor wires backwards.

put your factory lock/unlock wires back together. with your dmm, test your wires for lock and unlock.  find your lock wire first. cut it in  half.(at this point your locks should not be working from the switch in driver's door) next, meter both ends of the lock wire you just cut in half. with the lock switch depressed, your meter should show 12v. (this is your switch side) with the lock switch depressed, the other side of the wire should read 0v.(this is the motor side) [if you depress the unlock switch, while testing the lock wire you cut in half, your motor side will read 12v and the switch side will read 0v.] reversing polarity! by cutting one wire in half at a time, this eliminates any cunfusion as to lock/unlock motor side/switch side.

bw4150,right?     your mini relay pack that came with the alarm should be wired as follows: violet and violet/black -------12v constant

                                  green--------------lock motor side

                                 white--------------lock switch side

                                blue----------------unlock motor side

                                  brown------------unlock switch side

                         hope this helps!!!
