All:

I need HELP! I have installed my DEI Viper 550ESP alarm and have most everything working BUT the door locks.

Actually, the UNLOCK works, but the LOCK does not. I had done the following steps:

Step 1. Alarm Blue (Unlock) to LT GREEN/RED CAR and 87A Relay
Step 2. Alarm Green + 1.5K Resistor to 85 Relay
Step 3. Relay 86 (Fused) to BLACK CAR (+12V)
Step 4. Relay 30 to LT GREEN/RED CAR

What did I do wrong OR what am I missing?

Please advise ASAP!

Thanks.

I still need help. Please help.

 

Unlock works, lock does not. I have the lock going through a relay per DEI instructions + a 1.5K resistor. on the "30" side.

Please help!

 

as per DEI you should be using 2 relays, it's a type:H not a type:F
the wire does not require a break to lock, which is why unlock works and lock does not.

relay #1 (lock)

85 = green from alarm
86 = 12V+ fused
87 = chassis ground
30 = to car wire w/1.5k resistor

relay #2 (unlock)

85 = blue from alarm
86 = 12v+ fused
87 = chassis ground
30 = to same car wire

87a is not used on either relay and should have no connection.

Yah - I got it working! Yeah, the two relay things as posted did the trick!
