avital 2101 in 97 blazer

Dear All. I bought an Avital 2101 and would like to do the min istallation on my Chevy Blazer. According the Chevy schmetic my blazer has positive triggered doorlocks. I have an orange hot wire 12V going to the doorlock actuator swicht. Can this forum confirm this??? primary harness (H1), 18-pin connector BROWN / BLACK UNLOCK #87A NORMALLY CLOSED VIOLET UNLOCK #87 NORMALLY OPEN (INPUT) BLUE/BLACK UNLOCK #30 COMMON (OUTPUT) VIOLET/BLACK LOCK #87 NORMALLY OPEN (INPUT) WHITE/ BLACK LOCK #87 NORMALLY CLOSED GREEN/ BLACK LOCK #30 COMMON OUTPUT Which lines do I need to trigger positive triggered doorlocks? What means door lock common & unlock common. Do we have a sample schematic for positve triggered door locks? Thank you BR Bob

Don't use BROWN / black or white /black. The purple and PURPLE / black to your orange 12V+ constant. GREEN/ black to lock (light blue) and blue/black to unlock (white).Test before boxing up.

Thank you Harry, I have an old broken Clifford Keyless Entry harness in the vehicle, I would like to attache my cables there & not rip the dashboard apart. Here the schematic and the colors I added to cross. so the BROWN / black & white black will not been used? Can you confirm my crossing from Clifford to Avital 2101? BR Bob

Correct! Test before boxing up.

Does a Chevy Blazer 97 has a postive or neative triggered system?

Harry so the 97 Blazer has a negative trigger. I am conneting Violet & Violet Black #87 to +12V (GM orange cable) & conneting Avital GREEN/ Black (Lock#30 common output)to GM light blue & Avital Blue/Black (unlock #30common output)to GM white.

Are my schematics OK Why is my hot running into 87 and not vice cersa in 30 and 87 switches the relay?

Actually the Blazer is POS (+) not NEG but your wiring is correct. As for the other posts Test before boxing up.

Harry my door locks are working thank you but can you help me fixing to wire H1/3 & H1/4 Domelight Supervision relay. On my old harness from Clifford BROWN / Red is connected to ground. The clifford schematics says "connect to ground negative trigger pin swichtes". Does it means the Avital H1/3 will be connected to ground and H1/4 goes to the 12V circuit ? Thank you for the help

Good morning, I got it already. Light is working. now left over is the rear glass to pop off. BR bob
