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.

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.

shipped out at about 2pm today.

im sure dei would use diodes in the 451M since they are good odds they are gonna be used on dei brains.

i was not aware of the +/- to - change.

I always dioded them when they had that flip-flop (+/-) lock/unlock outputs.
Used to get problems with European BCMs otherwise.
Thank you Siemens.

Howie, No Diodes inside a 451m, just 2 micro relays soldered to a PC board and the wires soldered to the edge of the PC Board. Very Very basic.

r u sure there arent diodes wrapped up in the coil? it could be hard to see

I haven't taken one apart in a while but I don't remember seeing any diodes. I used to take them apart frequently when I only needed one relay. The micro relays were much nicer to hide than your standard relay. You just had to score it right down the middle and solder a new + onto the one relay. Then you had 2 nice micro relays that could be easily hidden.

There is enough room to solder in diodes. I've done it before, You just use a knife to cut the solder trace for your output wire and solder in your diode. You can also add a diode across the coils. Then I use liquid black tape and brush it over the board. Howie, the next time I modify one, I'll PM you if you want and send you send Pics.

Don't be silly been doing it for years with my $1.5 home made version of DEI's 8166 mini relay.
1 X 20 amp PCB relay, Omron etc, $1
1 X 1N4004 diode 0.3 cents e.a.
Cables, red, black, brown, yellow and orange from the bits box free.
38 mm sleeving about 10 cents each.

Ok. I received the 451M and I open it up and now I'm confused!!!! I have no idea what all the little resistors are for or even how to hook this thing up. I need help!

Thanks!

The resistors are for cars with MUX locking systems, ignore, the wiring instructions are next to the resistors and engraved on the module try reading the instructions, failing that plug it into the lock socket on your R/S, assuming type "A", purple and purple black to a 12V+ constant, GREEN/ black to lock and blue/black to unlock.
Tape up (insulate) the BROWN / black and the WHITE/ black.
So simple really.

haha, Howie sometimes I forget who I'm talking too!

Don't worry, I did a quick mirror fold/unfold on a Mits today, it just needs a POS pulse on either or both of two wires to fold/unfold so clever clogs feeds them off the lock motor wires and forgets to diode them.
Think what happens the next time he manually switches those mirrors..

Thanks for all of your help. The resistors threw me off! Got everything hooked up and all is working! Thanks all if you guys again!

sorry i aint been around, i had to go outta town.drove10 hrs straight there and 10hrs back with no rest.

anyway... glad to hear you got it all workin.

you gotta love those happy endings.

Now for my next quest! I have a Viper 160XV installed in a 2009 Saturn Aura and I had this one done by a pro and they wanted to charge me $60 to hook up the locks. Of course I didn't pay it and just use the factory remote. Now I would like to know what I need to hook my door locks up on this car.

White, NEG to lock, NEG via 1.5KR to same wire, location; driver kick or BCM, grey 72 pin plug (X1), pin 66.
You will need another 451, this time wired as NEG output, type "B" Multiplex.
And don't throw away the resisters!
Purple and PURPLE / black to a good ground.
WHITE/ black and BROWN / black, don't use.
GREEN/ black to white above.
Blue/black via 1.5KR to join GREEN/ black.
