theft deterrent..

[ltomasj]

can someone tell me if the theft deterrent is the same thing as we called car guard??
i think i just cut this wires, because i dont needed the alarm, is this something that vill affect something else importent?????

I'm not sure if your van has the ignition system hooked in to the security system or not, but out of curiosity - do you just not like these wires? I don't see any reason to cut them, unless there's a legitimate reason...

Not heard of car guard , but likely the same thing , in 95 GM used the VATS system on most cars but don't think they used it on Astro , it was 98 before it was common on an astro and it was called Passkey then , If you have an aftermarket system you would be doing yourself a favor by getting the wiring diagram for your system and then use it to determine which wire to disconnect , otherwise you may cause a problem cutting wires that you do not know where they go to .

thanks phantom, in sweden there is a little difficult to get some wiring diagram, and it shood be a big help for me if you could show me some diagram of the swap from 4,3 to 350lt, my astro is a -95, and the harnes from a -96 roadmaster, engine -94, the most connection are done, but it would be good if i have something to check whid, the last i need is some wrong wiring and FIRE!!!!

swapping the 4.3 to a 350 can vary in diagrams and it also depends on what exactly and how much was swapped during the swap , I am puzzled somewhat in that you say you have a 95 Astro which is OBD1 , then you say you have the harness from a 96 Roadmaster which is OBD2 and the engine is a 94 which is OBD1 ,,,why the 96 harness? ,,how much of the harness is used ? are you using the factory 95 ECM ? if not what ECM/PCM are you using? what make model and year of car did the engine come from? Do you have a chip in the key? most astros do not use the chip in the key , if there is a chip in the key a simple resistor placed inline can override the security system .

Are you having a problem with security and if so what type of problem and how did you determine the problem ? I don't recall a security light in a 95 astro to light up , how did you determine the matter of a security problem?
Do you have an aftermarket alarm/security system?
it is possible to modify the 96 harness to work on a 95 ,, so the question is , what exactly are the problem symptoms? and what makes you say it is related to security system? Can you take a pic of the wires you are referring to?

i dont now if the alarm does affect the ignition coil, i have solve the most harness problem, but i dont get no spark to the sparkplugs, it`s dead, all the things like fan, lights work, but not the ignition coil and also the fuel gage, maybee it that i try to use the v6 ignition coil?
maybee i must get a lt1 ignition coil!
by the way..the alarm is a delfa.
comming som pics soon.

Sounds more like your just not getting power to the gauge or ignition system. You need a wiring diagram from the engine donor vehicle. So you can check the hot leads for power. A service manual would be best. Some thing is just a little different between the van and the donor vehicles wiring.

You need to do some testing to find out where the voltage stoppage is , an alarm system could interrupt the voltage signal , do you have a model number of alarm?

You may have a broken or corroded wire/terminal , or broken wire in the starting circuit , the ignition module may be bad , check for voltage to the ignition module , and test if coil is getting 12 volts into it
