2003 chevy silverado viper 5301 wiring

I am about to start cutting wires and soldering on my 2003 Silverado to install the Viper 5301 remote start. Below are a few pictures of the dash taken apart. I was wondering if anyone had a picture of thoie viper remote start installed so i could see where ther ran the wires. This is my first remote start but from the pictures, is it the large guage wires (red, yellow, white, pink, orange, and brown) i will be conecting to? Also can i tap in right there or does it have to be behind/ on the back side of the harness? Thanks for the help

Also, I have a peripheral PGMDLBP bypass. I bought this one first but decided to go with the xpresskit because it was made by DEI like the Viper. Any input on the Peripheral?

Sorry for "stupid" questions but is the BCM the black box in the middle of the 2nd picture? Does it disconnect? I think i have seen this in another install picture but it looked like it was the back side of the box, not the side i can see in the picture? This should be where i connect the H3 harness wire, right.

The DLPKGM wires seem straight forward to the truck, i just need the black ground to kick panel and the Purple to the purple wire on the 2 pin OBD II correct?

Also, i have read that i should disconnect the battery AND that i shouldnt disconnect? I always thought it was safer to disconnect?

Thanks for the help guys...I'm gonna start the install tonught after work.

OK guys. I got everything hooked up tonight. Right now it is just put in place and wrapped with elec tape. I plan on soldering everything once i figure out whats going on. I hooked the battery up but i'm not sure how to go about programing it. I'm in VA and its 16 deg outside (they say 2 deg with wind chill) so i called it a night. When i tried to lock and unlock the lights blinked indie and headlight but it wouldnt lock or unlock. Also, the remote start gave me the error beep and then had 7 flashes? I will have all night tomorrow to work on it if you can point me in the right direction.

Thanks for the input.

Well i tried to get things programed today but no luck. I'm lost... I have all the wires hooked up. I'm not sure where to start. The lock and unlock isnt working and the remote start just gives me the 7 flashes error. I giess i'll start with the wires i have connected:

H/3

1 Pink to Pinka @ IGN

H/1

1 RED / white

H/2

1 light/green -

DLPKGM

Pink to Pink @ IGN

Violet/White - This is NOT hooked up? I dont know if i need this/ not sure what tach i am running.

Any help would be appreciated.

Below is a picture of my IGN harness and the wiress i am slicing into. There is also a Brown in the IGN that is hidden but it has nothing going to it. The  H/3 2 RED / White is connected @ Red IGN ( the IGN switch has 7 wires: 3 on the top Pink - Red - Brown and 4 on the bottom White - Yellow - Red - Orange) This H/3 2 RED / white is connected to the red on the top row. The H/3 5 Red & 8 RED / Black are connected to the Red IGN on the bottom row.

Here is a picture of how the truck looks tonight:

Also, i'm still confused on how to change it from Manual to Auto. Do i need to have the DLPKGM hooked up for this and should i have to program the remote? Right noe when i have the control plug hooked up, it constantly blinks blue. I also have the jumpers on the Viper vertical. Is this correct?

And, do i need the  Violet/whiteTach wire hooked up coming from the DLPKGM(its not right now)? I have the door lock and unlock hooked upfrom the DLPKGM to the viper 3 PIN. I'm using the D2D now, should i go W2W?

Thanks for the help!
