I purchased a remote start/security, proxy sensor, and bypass online with the intention to install myself but after looking at it, it's just so intimidating.  I've always been more than proficient with A/V so I thought I'd give it a shot.  I'm at the point where I'm gaining some knowledge reading forums and watching videos but the more comfortable I get, the more I feel like I'm lost if that makes sense.  Please help me.  I'll start with a few questions.
I've downloaded the install guide located here: 
Here
I see that I can use either install type 3 or 8 (3 being hard wire and 8 using T harness).  I called Flashlogic to find out if I need to buy their tipstart harness or non.  I was told that I can't use the t harness because it's a manual.  Is this true?  I was hoping to eliminate as much splicing and searching by using the harness and hardwire the remainder.
Assuming I can use the harness, is it as easy as plugging the cables into the flcan, plug it into the data port of the brain, and connect the t portion to the ingnition harness?  Followed by few hard wires remaining?  
I'm sorry this is so long, I just wanted to be as clear as possible.  Any help would be great, thanks.
I don't know that they make that t-harness any longer, so that may be why they say that. Also the new version for that vehicle's T-harness does not work on manual transmissions.
If you can find that t-harness, you could use it. You will need to hard wire some parts. Also it may help if you list the type of vehicle, my guess is a jeep or ram.
It is a simple install if you follow the directions as they have them laid out.
