Installed a Viper 5901 in a 98 Honda Civic. My trunk pin input on the alarm requires H1/7 to be grounded when armed (normally closed). The alarm will go off when there is no ground. Does this sound right? I believe the trunk switch is grounded when the trunk is popped open. Is there a program setting I need to change?

 

H1/7 blue is a neg.(-) input trigger, [instant trigger], it can not be programed.
Pin 4, of "Remote start input, 5 pin connector, [gray] can be programed for NC/NO neg(-) input.

Where did you connect the H1/7 blue trunk pin/instant trigger lead too? 94

 

My H1 connector has 12 pins. H2 has 18 pins and H3 has 10 pins.

I know that the Hood Pin Connector can be programmed NC or NO. So if needed I can connect the Trunk Input there also.

I have H1/7 connected to my Green Audio connector Pin B2 which is the Trunk Latch Switch.

To test my H1/7 input, I grounded that input. I armed the alarm, removed the ground and the alarm went off saying the trunk was open. Knowing that it wants to see a ground, I might just use a relay to reverse the trunk input so it gives a ground signal when the trunk is closed and no ground when the trunk is open. I just thought it was weird that H1/7 alarms when there is no ground signal....

 

What color is the lead at the "Green Audio connector Pin B2"? 94

What happens if you arm the alarm with the H1/7 trunk pin trigger lead not grounded and then ground it? 94

 

B2 is the light green wire.

When I arm the alarm with it not grounded, my keypad says the trunk is open. When I ground it while it is still armed nothing happens.

If I arm the alarm with it grounded, my keypad is fine. When I remove the ground the alarm starts to go off.

 

Then problem is the alarm, where did you get the alarm?

Yes you can use a relay to reverse the polarity, or use the hood pin input, [a diode would be needed if you do not want trunk/hatch light turning on when hood is opened. 94

 

Well I believe everything else works on the alarm. I bought it off Amazon from user buy12voltcom.

 

OIC, probably a recall for salvage unit that has worked itself back into the system. 94

 

Yea, you're probably right....I did get it for super cheap compared to what they cost at best buy. Thanks for all the help!
