I am curious what other have done when you need to tap the same wire many many times.  For example when hooking up many accessories to the 12volt accessory wire I don't want to t-tap 5 to 6 times and destroy the wire.  I would like to tap once and then  join all the wires on that one but I have not found a good method yet.  What have you done?

For a start WE don't T-tap!
Bad electrical connection, bad mechanical connection and frankly dangerous when it comes to high power.
Staggered solder joints, cut the source and solder and heat shrink sleeve.
If you can't sleeve, solder and wrap with Scotch 33+ also cable (zip) tie the joint.

If I'm adding multiple wires at one time I try to solder them all together so there is only "one" tap.  If I'm adding more later I typically will try to add the new wire to the wire added earlier.  That way you arn't hacking up the wire.

Why not just solder tap into the factory line ONCE than use the leader/pig tail just created as the source wire for the muliple new taps. This way you minimize the distrubance to the the orig wires.

I have no idea how much current you are planning to add to the possibly near capacity wire, but I would use the switched wire to trigger the relay and supply the relay with adequate power from the battery.

And may I add... CUT your tape with a pair of dikes, NOT pull or tear it.  When you tear it, the end loses it's adhesion and the end wont stay down and it'll start to unwrap before long. 

Start just below the joint, overlap wrap the joint ending PAST the joint.
