90 astro van keyless entry

im installing a (aftermarket generation aga0801) keyless entry on my 90 astro van. it will unlock but wont lock. when i hit the unlock button on the remote it lites up my test light, but wont light up my test lite on when i hit the remote lock button. i am hooked to the light blue (lock) and the BLACK/ white (unlock) im not using the engine cut off at all. i cant figuar out if im making a mistake or if the entry system is broke? here is 2 bad photos of the wire diagrams.

thanks thegoose

i hooked the red and both yellow wires to the positive like in the diagram, i thought it was weird to hook both yellows to the positive but thats what it says to do.  and i did check the wires with a test light to see that i had the right wires.       im wondering if not hooking up the white - acc, blue/black - trunk, yellow - engine cut off, pink - siren, might have something to do with it?????????????

Doesn't the YELLOW / Black have to go to Constant 12 Volt + also?

sorry thats what i ment the red and the yellow and the yellow/black all to the positive 12v

its possibly it is a programing problem the instructions are a bit confusing to me. im going to try to program it again if it dont work im going to assume it is defective. unless this has happen to any one else.    

thanks for your help

i did check the other wires (excpt the yellow/black and yellow that are hooked to the positive 12v) none light up.
