RS- proper method for splicing?

Ok, i've installed a handful of alarms in cars before- mostly using the snap splice blocks.

Last night I decided to tackle installing my remote starter.  After about 3 hours of working on it (it is working, yippie) i have a new respect for installers.  On the alarms most of the splices are minimal gauge and easy to work with.   On the RS it seemed like the reverse was true- most are heavy guage and very difficult to splice.

So, how do professionals tie into the wires coming off the ignition harness?  I'm just curious.  I cut mine and resoldered them with the new wire attached.  It works, is sturdy, is ugly, and was a royal pain in the ass to do when you have only like an inch of wire to work with.

Inquiring minds want to know- how do you guys do it?

ok.  i'm pretty good at soldering- and i was using my trusty butane Ultratorch - that thing really heats up fast.

It was more the lack of available wire to work with.  I mean those harnesses are pretty much built to the centimeter in wire length, so it was very tight to work under the column like that and add the fact that the wire gauge was so big, it made it somewhat difficult to bend them into position.

As I said, all of you installers have earned a new respect from me!

I solder the remote start wires period:

I strip back the wire an inch or more, then take an awl, or my probe/test light and make a gap between the strands:

Next, I take the wire that I am soldering to, and insert it and "wrap" it around and flatten it and solder:

Last step is to tightly wrap it with some 3M super 33 tape:

I've learned that if you're in a tight spot and you have no space to wrap it with the roll, get a butt splice and make your own "mini roll."

And voila !

That's my method.
