I am going to install a sony deck in my 98 accord ex. I bought a wiring harness and have almost all the wires matched up to the wires out the back of the new deck. On the harness i bought, there are three wires that i don't know what to do with.

They are:
Blue
Orange
Orange (labeled positive dimmer)

On the deck harness, i have two that i don't know what to do with.
They are:
Blue with white stripe
Blue (labled ANT REM MAX 0.1A) with a clamp connector at the end.

So, i need to know which remaining wires match up with which.

When my subs where install, the REM was matched up with a white wire that was in the factory harness. (still had the factory HU then) Do i need to move the REM to the Blue wire labeled REM or does it not matter.

Finally, what method do you recommend for connecting the wires. Usually i just use the electrical tape method but i think i should use a more for secure method for something as important as my HU. Any input is greatly appreciated because i wnat to start listening to music again while driving.
