Default 791xv heater doesnt work

Alright, I found the 95 diagram, I have remote start but then the heater doesnt work. I can't find my viper 791xv wiring diagram. Can anyone shoot me the link for the diagram or tell me what wire i misdid.

MM&Y of car it is in?

Viper 791xv install guide... http://www.directeddealers.com/manua...564V_07-05.pdf

If heater, [blower motor] is not working it is because you have not connected an output, [or enough outputs] from the remote start, [acc. or ign.] to the correct lead(s) at the ign. switch harness.

Some cars only need one acc. and one ign. output connected for engine to remote start, others need 2nd acc. and 2nd ign. for blower motor to work. 94

Thanks, and another issue, it'll start by turning the key fine, but sometiimes it'll have a hard time starting by remote start. Common problem?

It says (-) 200 mA ACCESSORY RELAY TURN-ON

do I just wire that wire to the accessory wire behind the ignition?

no that wire is used to add a relay to that circuit if needed.
on the 791 there should be a 14ga orange wire from the relay pack (it with the purple green pink red wires)-that is your accessory wire output wire.

There are four leads at the ign. switch harness that need to be connected to...

White - 12V+ constant, both the reds and red/white from relay satellite are connected to it., or what I will do is run a fused 8ga from batt. and connect all three to it instead of the white ign. harness lead.

Black/white - starter, either just the purple or cut it and use the purple and green.

Black/yellow - ign., pink from relay satilite.

Yellow - acc., orange from relay satilite.

Unused leads in the relay satellite harness should be removed by de-pinning, [pink/white and possibly the green, if not doing starter cut].

As mentioned the orange, 2nd acc. output is not needed, in fact none of the leads in that harness are needed.

What exactly do you mean, "it'll start by turning the key fine, but sometiimes it'll have a hard time starting by remote start" by hard time, will it not crank the engine or will it crank the engine but not start?

How did you make the connections of the remote start wiring to the cars wiring, solder??? 94

Your car harness should have a white with a black stripe. Tag the orange wire to it. This is the second accessory wire.

Also when doing a da integra this wire must be hooked up or the cooling fans will not come on causeing the the car to over heat. I thought I just throw this out there.

White/black???

White/black is the acc. on a 96 Civic, the yellow was a 2nd ign., [sometimes referred to as acc. 1 with white/black being acc. 2] but I have not seen a white/black on a 95 civic.

Hanmin... what month was your car built? 94

what month? its an eg? Idk.

What i meant is that if i pressed the remote start button, the starter would sometimes start. When the starter clicks, it'll just keep clicking like its trying to start, but it is possible to start with the key?

I know its weird, The starter wire and the 12 volts wire is in the same plastic harness. And there are three wires in the other.

As for the da, I learned this on my old shop car. When remote started the car would sometimes over heat and the heater did not work-did not care about the heater or ac. I went on a 2 hour chase wondering why my fans did not work. Then I traced the circuit and found out they are on the same one. After the car was over heating and I turned the key on and the fans came on. This is also not listed on directechs if you have the permission to use it.

I didn't fully wire the ignition for the remote start, theres 2 acc wires and I only wired one of them... My excuse? I did this when I was 17=]
