1992 Chevrolet K1500, Avital 4105L Remote Start Install

I have an Avital 4150L i was installing and ran into issues. I only have the heavy gauge relay 6 pin (all 6), the ground from the primary 9 pin (blk), and the tach input, brake shutdown, and parking brake input (purp/white, brwn, blk/white) from the 5 pin connectors wired in. It seems to program right when i did the remote and tach learn, but when i press the remote start button it just clicks and flashes my dash lights for like half a second. I do not see it flashing an error code. I assume i need to connect atleast the horn and lights or something, was trying to just get it to work before getting into those but thats about all i can think if unless you guys know whats up. Thanks in advance.

Avital 4150L ? Typo, perhaps a 4105L? The wires/colors you listed sound like a 4105L.

If you connected the Black/White wire to the vehicles Parking Brake wire, did you put the Parking Brake ON when you attempted a R/S?

Connect the Parking Lights and try to count the Parking Light flashes.
Parking Lamp (+)   BROWN   (+) AT HEADLIGHT SWITCH
Make sure the 4105's parking light jumper is at the (+) position.

LED Flashes        Shutdown Mode
I flash............Timed out
2 flashes .........Over-rev shutdown
3 flashes .........Low or no RPM, low battery [voltage and virtual tach modes)
4 flashes .........Transmitter shutdown (or optional push button)
5 flashes .........Hood Shutdown (5 pin Gray wire)
6 flashes .........Brake Shutdown (5 pin Brown wire)
7.flashes .........Neutral safety shutdown (5 pin Black/White wire)
8 flashes .........Wait-to-start timed out

Soldering is fun!

Yeah sorry it is a 4105, the black/white i have just grounded along with the ground from the main harness. Connected the lights and they flash 1 time as soon as i press the remote start and that is all. The actual led on the unit does not flash anything untill i miss with it enough that it just starts to constant flash. Now it beeps when i press buttons though so i guess thats progress maybe ha. I tried swapping my brake switch to the other wire to see if maybe that was doing it but it does the same thing for both wires.

The Brake wire should be :
Brake Pedal   WHITE (+)   AT SWITCH ON BRAKE PEDAL BRACKET   
Verify with DMM.

Perhaps you could list your main ignition harness connections.

Yeaaa turns out im just stupid ha, i mistook a light grey wire for the white at the brake switch, swapped that and now it works. The diagnostic LED not working is kinda odd but hey so long as the truck starts im happy. Thanks for the help man.

Thanks for the update. Not unusual for the wires to change colors slightly with age... Thirty + years is pretty long.
