I've installed a Clifford 50.7X (same as Python 574 and Viper 5704) a month ago and remote start works fine, except the HVAC doesn't work.
The radio works fine, and I thought the HVAC and radio shared the same accessory output(white/black on my 00 Civic).

I haven't had time to check my wiring at the moment, but anyone may have an idea of what's wrong?
Is it possible it's related to the ignition 2 wire (yellow)?

 

You need to hook up the yellow wire on your ignition harness. To the extra output of the remote start heavy gauge wire harness.

Thanks guys. Just to make sure, I would assume red/white would be to constant 12V and pink/white to yellow at iginiton?

H3/1 Pink - Ignition 1 Input/Output
H3/2 Red/White - Ignition 2/Flex Relay Input 87/+12V input
H3/3 Orange - Accessory Output
H3/4 Violet - Starter
H3/5 Red - Ignition 1 Input
H3/6 Pink/White - Ignition 2/Flex Relay Output
H3/7 Pink/Black - Flex Relay Input 87A key side of flex relay
H3/8 Red/Black - Accessory/Starter Input/+12V input

 

Yes, and should be "programed/wired" as an accessory, [hot in run but not start] you do not want the blower motor on when starter motor is cranking the engine. 94

 

Thanks, I found out I've hooked the red/white wire to ignition 2 and with no connection on pink/white. I just connect red/white to const. +12V and pink/white to yellow ign2, and it works great.
