avital 4103l power door locks

I have a 94 Chevy G20 sportsvan and I just installed an Avital 4103L remote car starter. I have everything working except the power door locks. I have them hooked up and the box clicks but the locks don't work when you press the buttons on the remote. I need help!

until you tell us how you connected the lock relay wires to you locks, its hard to diagnose what went wrong.yuk

I just hooked the wires up to the lt blue and black wires like the paperwork said to do. I did not install any kind if relays. If I have to install relays, how do I so that, what kind of relays do I need and how do I wire them up? I'm a mechanic of 15 plus yeas but have never hooked or wired relays or anything in.

the clicking in the box is probably the parking light relay flashing the parking lights.

where did you hear that the blue and black wires were the ones to hook to?

The door locks use a positive trigger. The Avital only sends a negative trigger on the lock wires. You will need relays to convert the negative signal from the Avital to a positive one to power the door lock wires. Power Lock      lt. blue      +      door boot or behind cluster Power Unlock      black      +      door boot or behind cluster You will need 2 relays, one for lock and one for unlock. The (-) trigger goes to either the lock or unlock wire of the Avital. The 12V+ Output goes to the corresponding door lock wire in the van.

Well that sounds like a plan. I may also try and wire up the relays cause I do have a few laying around for the time being. When I get something hooked up ill repost and let you know how it's working! Just wanted to thank everybody for their help! Thanks people!

just make sure you dont miswire something and blow your unlock circuit.

if you look at install manuals for most DEI alarms and remote starts, the lock wires alternate as pos and neg pulses. your is the first DEI i have seen that only does neg pulses.so i learned something myself along your post.

some vehicles use neg pulses, some pos pulses, and some use a certain resistance on a single wire to communicate lock or unlack. there are all kinds of different systems.

most older GM vehicles dont have a door lock relay at all if they are only 2 doors and have no factory alarm or keyless entry. those cases you must have something like a DEI 451M or use a brain that has built in lock relays.

most other vehicles have a relay that can be operated directly from the brain in some manor or the other.

THEN WE HAVE YOUR VAN.  LOL....

multidoor, vehicle has its own relay, but you have a brain that only pulses neg. so the 451M will turn your neg into a pos.

search the "Downloads/Manuals" section of this forum for "451M" and open the larger file of the 2 that come up.

the smaller file does not pertain to your situation.

you will use the "type A"  description. tape the unused wires so they cant touch anything else and thats it.

i have the package all ready and will get it in the mail tomorrow morning. you may have it wed.

Sounds like I should just wait for the box. I do have a good idea on how to wire the relays but don't want to run the risk of ruining something! Relays and resistors are not a strong point for me. Done lots of light, radio and amp installs with no problems but I understand how that works! This is a totally different animal in my book. I'm a jack of all trades but seeing you guys lay this stuff out and telling me how these things work, I want to start learning how to do this and for that I want to thank everybody on this site for being so helpful!

Itsyuk, DEI dropped flip-flops after the 5901. Now could you send me some 451s (think of it as lend-lease) I used my last today on a Beemer + 5704 (Euro E36 was POS locks). On a serious note does the 451 have internal diodes? Because it bloody well should.
