  Going to be installing Crimestopper Rs900VI in my 00- Chevy. I have Crimestoppers GMATAII  bypass. Could someone tell me where the Passslock module is located and any other tips for an amateur?

Thanks for any info.

Thats a really easy truck to install on.   I would not use the GMATA, I would get a PLDATA, which is easier to install and more reliable.  Also the locks on your truck are + and the output from the RS900 is -.  You can convert to + with relays or get a door lock module (cs-6600 or DEI 451M).  The GMATA has pretty good directions, I have run into a few problems when using that module.  Here is the wiring diagrams and locations for your truck.  Post on how you do..

Notes:
NOTE: If you have a 2000 Classic Pickup, refer to the 1998 Full Size Pickup.  NOTE: This vehicle has the passlock II immobilizer system that, when adding a remote start, must be interfaced with. Use DEI part 555t or 555L.  *1 The BCM is located behind the drivers side of the dash. The plugs on the BCM face towards the rear of the vehicle. The parking lights are in pin A5 and the headlights are in pin A11.  *2 Use tan for the drivers door located in pin B4 of the purple plug, and for the passenger door it will be a orange in pin B2 in the purple plug or dk.blue/white in pin B11 of the lt.blue plug, must diode isolate these wires.  *3 ECM is located near the battery, down low, between the fender and the fan under the black plastic cover. On the 4.3L, the tach wire is at pin 20 in the connector labeled 'red', and VSS wire is at pin 3 in the connector labeled 'black'. On the 4.8L, 5.3L, and 6.0L, the tach wire is located at pin 10 in the 'red' connector, and VSS wire is located in pin 50 of the 'red' connector.  *4 Also found in the purple plug of the BCM.  *5 Diesel wait to start wire is dk. blue (-) located at the instrument cluster 'see direct fax document #1090'.

Oh... and solder all your connections.  And do not use the "Smart tachless mode" on your truck.  I have installed MANY RS-900's, and 90% of the time the tachless mode works good, but not on Chevy trucks.

Thanks for all your help Haku. I have the starter wired in just need to do the bypass, hopefully tonight. I more question : does the green wire from the Rs900 "(-) start activation input" end up getting connected to the yellow wire of Gmata "(-) ign input (ground when running)"? And sorry one more White wire from Gmata "additional ign output for white or green wire at column" connects to ign 2?

Thanks again for all your help.

No, you do not use the green wire from the RS-900.  You use the yellow/black from the RS-900, its a - ouput when running.   The green wire is an input to the unit to activate start from another source.  And if  remember correclty, you dont need to hook up the white wire from the GMATA.

Thanks again. I guess i'm in over my head. Does green from rs900 "(-) start activation input"  need to be connected at all? If so to what?

Thanks again,

It does not need to be connected.  It is another start activation input, and not needed. (If that wire sees a negative pulse it will start your truck)  And NO, you are not over your head.  You will have no problems.

Thanks alot. Working on it now. Your a life saver. Someone told me not connecting the white wire from Gmata "additional ign. output for white or green wire at column" would cause the security light to stay on . Make any sense?

Thanks again,

Arbour

you donot need to connect the white from gmata  but you do hook the pink|white from your 900 to the white ig2 (small white ) at ig harness and make sure the jumper is in the ig2 position

Sorry for the lack of response, had problems and haven't been able to get back to it yet. Truck would attempt start ,but no go. I believe its a bypass problem. But the other strange thing was the led never lit when trying to teach and the parking lights never flashed either. Going to go through it all agin this evening.

Thanks for all the advice.

Success!! Thanks for all the help! Only one little quirk. When remote starting and then getting in and driving, security light stays lit. But not when starting with key. Any ideas?

Thanks,

You have to either relearn the bypass module or isolate your starter wire from the RS unit to the vehicle as this would cause feedback into the ignition system.

Thanks Jeff. How do you go about isolating starter wire?

Use a SPDT relay and wire like this:

  • 85 to starter wire from RS
  • 86 GROUND OUT WHEN RUNNING WIRE from RS
  • 87 Vehicle start wire
  • 30 12 volt CONSTANT fused at 30 amps
  • 87a not used

This has worked for me in the past, but just make sure about your resistance first on the module.Another thing to look for is that your GROUND OUT WHEN RUNNING wire is infact strong enough a signal to engage the module. Use a DMM to test for absolute ground on the chassis and on the module.

When does the light turn on? If it turns on after you put the key in and hit the brake, then you need to turn the key to start before hitting the brake. You will want to have an anti-grind feature installed though.

This is just a thought, try Jeff's idea first.

Jeff, i've never tried that. What were the circumstances that you needed to do that. I may want to try that sometime. The only 2 cases i've ever had that problem was on a grand am and a malibu and turning the key to start solved the problem, but that doesnt sound related to your solution.
