I have a 67 Camaro using a compustar CM4000 brain

upon initial power up the siren was super faint but going off, led flashing. I am not sure why or what is wrong

options added
-starter kill RELAY
-door lock actuator RELAY
-trunk popper    RELAY
-light flash
-door pin
- hood pin
no remote start cause it is a carburetor car

-forgot to add ground wire at intial startup but realized right away

-what would cause that problem, and now it does not respond unless you swipe the power wire 3-4 times across the battery and then the alarm siren fully blares for 3 seconds, and remotes do not respond at all, cant even get to valet mode.

all that was last night this morning went out and put power again and only connected
-12
-ground
-ignition white
-ignition green
-GREEN / WHITE to lights
-antenna
-valet
-pager on windshield

-first time it turned the led on steady along with the valet button, but once I took the power away and reconnected there is no more led's either.

-I can cycle the ignition 5 times for valet mode and hear the internal relay click, but no lights flash or no remote learning, any ideas please I am stumped

My thought is the module ground back through the chassis is resistive. With the very low current of the module, any resistance could cause problems.

Just for grins, run a temporary ground wire from the module ground direct to the battery neg terminal, and run your tests again.

what will that do and besides I have tried several times to program the remote but it will not recognize it and I have only plugged in cn1 and all others out except the antenna and led, and valet.

Do you think the antenna is fried and also if I sweep the +wire a few times I can get the alarm siren to blare but once disconnected it does not do anything.

Also when I cycle the ignition 5 times the brain relay's click so not sure at all now thinking maybe the antenna is the problem

tekin, what davep is suggesting is by running a dedicated ground from the alarms ground to the battery negative post you are making sure there is not a ground issue keeping the system from working.
davep probably knows like I do, that on a 67 Camaro just due to age things like grounds and such can become poor.
Let's say you are grounded to a bolt on the steering column. This bolt is attached to a bracket bolted to the firewall, then somehow from there, the electricity or the ground path needs to get back to the cars battery. Some Camaro's had ground straps from the firewall to the engine and who knows, someone might have removed them or they are so corroded they are not working like they should. Some Camaro's also had a small ground wire off of the battery bolted to the radiator support. The radiator support is then bolted to the fender, and the fender bolted to the firewall. If all of these parts were painted off of the car, mechanically things might be fine but electrically it's not.
Try a dedicated ground wire from your alarm brains ground wire to the battery negative and for the test just run it outside the car. It;s just a test and it may or may not work but it's worth a try.
If you don't have a solid 12 volts AND a ground, then things will not work, may work, or work weird.

Because in a 1967 the front park lights are a separate circuit from the tail lights. The front are only on in PARK position. In HEADLIGHTS, the front turn signal park lights are not on in a 67 and earlier. 68 and later the front markers are part of the tail light circuit.

At the headlight switch, jumper the purple and brown wires together. The front lights (purple) will now be on with tail lights (brown), including in HEADLIGHTS.

If you only want the front lights to flash with tail lights from the alarm (not be on with headlights) do this:

Get 2 5Amp diodes.
Connect the non-band ends to the (+) white light-flash wire on the alarm.
Connect one band end diode to the brown at light switch.
Connect the other band end diode to the purple wire at light switch.

Funny that I remember this. 1968 and later don't have this.

Dave thank you very much for the info, but your PM was a lie you know everything hahahahah

I wanna do this
"If you only want the front lights to flash with tail lights from the alarm (not be on with headlights) do this:

Connect the non-band ends to the (+) white light-flash wire on the alarm.

BUT YOU MEAN THE GREEN / WHITE wire for light flash right of the main harness

Sorry. I'm a DEI guy, and DEI light flash is white. Isn't everyone???

Yep. Whatever color your light flash wire is. I assume it is (+) output, and you did NOT use an external relay.

Date Posted: December 04, 2015 at 2:14 PM
yes sir it is GREEN / WHITE (+) output

DEI GUY, man I just bought a brand new in box viper 5902v alarm/start combo I was gonna put in the car and the remote charges with wall power but as soon as you disconnect it from the wall there is nothing on the display of the remote it is the 7941v. It is the 2nd box with same problem from BESTBUY and now viper wants me to mail it back at my expense to the USA office from Canada. That is not right man Viper warranty sucks just my 0.02 cens

Whoa there big guy.

When I said "I'm a DEI guy" I meant that's the product I'm familiar with because that's the make of gear I use. I'm not a DEI employee.

Your post is directed at me as though I WORK FOR DEI. I DON'T. And if I did, I still wouldn't appreciate that post in that tone because I was voluntarily helping you as an individual WITH A NON-DEI PRODUCT no less.

DEI's policy regarding their warranty is well established: If one of their Dealers doesn't install it, it has no warranty. Seems clear to me. Your beef is with BestBuy. Not DEI, and CERTAINLY not with ME!

I didn't appreciate that at all. Hope someone else helps you out with any future questions. I'm done.

I wanna add

--a trunk light but there is no switch in the trunk but I did add a trunk pin switch to the alarm, can I use that, if so how do I wire it and do I need a relay???

--I have a interior dome light and the light comes on when the door opens but it shows a neg trigger and I want to add a courtesy light under the dash for the foot well how do I wire a new bulb socket there???

I have two questions:;

--I wanna wire a light to the foot well of my car but the wire is POS+ just wondering how to do this??

--I want to add a light to the trunk when I open the trunk and would like to use my trunk pin(connected to the alarm) as a switch to open and close the light, any diagrams for relays or resistors????

not sure why my other post was deleted as my subject line got cut off

Also the 5902 hasn't been "brand new" for 3 years at least.
Trunk pin switch to ground, wire to one side of light, other side to 12V+ constant.
Wire a foot well light in parallel with your dome light.

I have no idea about the door pin your comments are somewhat vague to say the least, just do what I said in each instance then no problems.

I'll throw this out but maybe think about registering and introducing yourself at https://www.camaros.net/forums/ as this site deals more directly with the Camaro body style. Not that this forum should not be used but it may give you some more added info for things like adding the extra interior lights which on some Camaro's were standard or optional. I've read threads on that site and you are not the only one wanting to add underdash lights and I have seen them show where to tie into the wiring and with the proper parts, it's pretty much a plug and play upgrade.

Touching on adding a trunk pin switch is you may want to place it inside of the weatherstrip channel to keep it more protected. Since the first generation Camaro trunk opening does not easily lend itself to have a pin switch added, you may have to make a custom bracket and have it resting against the trunk hinge or maybe think about a magnetic type of switch.

Thanks Jim, those beasts are rare as rocking horse you know what this side of the pond, I'm suggesting proper practice but our friend doesn't appear able to follow, I wouldn't mind betting some are even pre-wired for floor/puddle lights.

On the first generation Camaro they had all kinds of options and if you got the right parts you could add different options like the underdash lights, an underhood light, a trunk light, and so on and GM designed these things to where they didn't have a mechanic cutting into a wire to make a connection but designed it to where it was easily added. For instance the trunk light, in the trunk there is a two wire plug that when disconnected, allowed another plug to be put in there and then it gave you a single hot wire out of it that you ran to the trunk light itself. The trunk light was designed with a mercury switch in it.

Off the subject here but the other side of the pond seems to be getting more of the these types of cars from the US. I had a buddy of mine a few years ago that was selling his 55 Chevy and a person from the other side of the pond bought it and this car will probably never come back to the states.

Funnily enough classics yes there were quite a few first gen Shelby, Camaro and Firebirds. I've even done an immobiliser on a Belaire and yes it WAS blue and white!
Nowadays nearly everything is the same, GM with Vauxhall/Opel and Ford all the same, Fusion = Mondeo etc.
Fiat tried to import some US Chrysler here but apart from the PT Cruiser and the Voyager the rest were a POS and never sold, they only import the Liberty and the Grand Cherokee now.
Let's be honest the only Fiat product that sells outside of Italy is the 500 and that's a POS compared to the Mini. (AKA 2 Series BMW).

hey guys I am following you guys but the thing is built a bracket and the trunk pin is working so I just wanted to tap that wire for the trunk light and as for the interior floor lights I tapped that wire also and I only have ground there when the door is closed. that is what I was trying to tell you




Posted By: howie ll
Date Posted: December 09, 2015 at 3:30 PM
Good Lord I've already told you how to do it, not repeating myself.
