viper 5901 confused

I would like to start by saying hi to everyone.

I have a 2000 ford crown victoria police interceptor/base

I purchased a viper 5901

My first question is what are flex relay on the (h3)10 pin harness? are they associated with the (h2)11 harness?

also where would i connect h2/10,11,12,13,14,15,16,17,18...

Sorry about all the questions i never installed a alarm/auto start before but in confident i can do it done subs amps and cd players before if im patient.. i would appreciate any help

I don't exactly remember the pin numbers as it's been awhile since I've put one in, but this is how I remember. The newer DEI alarms have the Flex relay for a variety of reasons. The RED / White large gauge wire is the input (pin87) of the flex relay and the Pink/White is the output(pin30). This basically means if you have a positive 2nd ignition or accessory, RED / White goes to 12v. In some chrysler cars, they may have negative ignition or accessory. If a bypass is not available to do it for you, you can simply connect the RED / White to ground. Alternatively, if you have only one accessory and one ignition, this is not needed and you can terminate both the RED / White wire and the Pink/White wire. Remember, if you connect it to a second accessory, to change it in the programming. It may cause issues, depending upon the vehicle.

A flex relay is there for when ignition switch isolation is required.

Also to the OP could you list the wire colours so we can help u, we don't always have a manual in front of us when we come online.
