Hey, I have a Viper 5301 that I plan on installing in my 1999 Buick Lesabre. I've done a ton of research about my car and wiring, etc. Currently I am stuck on finding the rest of the wires I need. I'm not sure if all of them are required and which will need relays or anything else. Any help would be much appreciated.

Here's a link to a PDF of the excel spreadsheet I've made so far: https://66.66.21.40:81/wiring.pdf

Green means I'm 99.9% sure that's the wire I need, along with the location in my vehicle and whether a relay or additional attention is needed. Yellow means I'm unsure if it's the correct wire and/or location. Blue means I will have additional work versus just connecting wires or relays. Purple means I believe that connecting that wire is optional (such as a optional accessory). Last, blank means I haven't been able to figure out the purpose of the wire coming from the Viper unit or that I haven't been able to find it in my vehicle.

Thanks!

H3/5 and H3/8 need to be connected to Red 12 volt(+) on ignition switch harness. I don't believe H3/2 is needed

Thanks for the help.. I've spent a bit more time researching and I've pretty much figured everything out. The only things I'm confused about is the door lock relay connections (at the bottom of the PDF) and the light flash isolation wire, which is H1/4.

If anyone could review if I chose the correct wires for the door lock relay, as well as explain to me H1/4, that'd be great.

I upgrade the PDF -- green meaning I'm 99% that's the correct wire and location, dark grey meaning it's optional, light grey meaning I COULD hook-up the function but I would never use it/would make no difference to me. Oh and the star just means I'll need to use a relay.
