I had an older viper remote start installed, and had no issues, but I'm a little confused about the ignition harness wiring for the 5901.

My truck has the following wires into the ignition harness:

12 Volt White and WHITE/ Red

Starter Black

Ignition 1 BLACK/ Red

Ignition 2 BLACK / YELLOW

Accessory Blue/Red

For the 5901, I understand I will connect violet to the starter side of black, and green to the ignition side of black. No issues there. I also know I will connect H3/3 (orange wire) to my accessory wire (blue/red).

I'm confused as to which wires go to the 12V constants, and which go to ignition 1 and ignition 2. I'm guessing that the following wires require 12V constant in:

H3/2 RED / White (Flex Relay Input)

H3/6 Red (ignition 1 input)

H3/9 RED / Black (Accessory/Starter Relay Input)

And for my ignition 1 and 2:

Ignition 1 H3/1 Pink (Ignition 1 Input/Output)

Ignition 2 H3/7 Pink/White (Flex Relay Output)

Does all this sound correct? If so, is there any need for the H3/8 Pink/Black wire (87a Flex Relay Input). I think it's the flex relay idea that has me confused. Thanks for any input.

H3/7 is not used. Factory default programming is Flex Relay = IGN2. Should be good to go. posted_image

I apologize, but did you mean to say H3/8 is not used? Everything else I mentioned seems correct? I really appreciate the fast response.

Yes, H3/8 Pink/Black is not used. Sorry, for the typo / confusion. Everything else looks fine, you have a good handle on it.

just make sure you power ALL 3 red primarys... Red, RED / White & RED / Black.... and you should be good to go....

I have a 2003 Toyota Tacoma and I am in the process of installing a 5901. I had a different Viper remote start before, and there was one thing that always bothered me that I was hoping to correct when I installed the 5901. I always leave my headlight switch on, and the lights turn off when I open the door. The issue is if I remote start my truck, my headlights turn on automatically. If I let the remote start time out, or if I shut it down from the remote, the headlights stay on because there is no door trigger. I did a search on here, and found a post where it mentioned using the factory alarm arm output wire to the door trigger to shut down the lights.

If I did this, would it set off the alarm, or would it ignore it because it happened at shutdown?

If my door trigger is negative, can I just connect straight to it, or would I need a relay for some reason?

Thanks in advance for your help.
