i recently bought a aga-1201 for my 1990 gmc full size pick up, same alarm as in this post https://www.the12volt.com/installbay/forum_posts.asp?tid=88545 .

i am having a problem hooking up the keyless entry also, i can't seem to hook it up with out blowing the fuses. i treid relays and every possible combo i can think of.

any help would be greatly appreciated

Try this way..... Chances are you have the switch and the motor wires backwards... (on the wrong pins of the relay)

On the alarm there is a 10-pin connector primary harness.
the pin are as follow (by manual)
pin 1: brown wire:siren output (+)-this is obvious for me
pin 2: white wire: parking light output (+/-) relay. do i need a relay then and then connect the relay to the parking light? or can i just connect it directly?
pin 3: violet: unlock #87a normally closed
pin 4: blue/black: unlock #30 common (output)
Pin 5: BROWN / black: unlcok #87 normally open (input)
pin 6: violet?black: lock #87a normally closed
pin 7: GREEN/ black:lock #30 common (output)
pin 8: WHITE/ black: lock #87 normally open (input). pin:

9: red constant
pin 10:black system ground
