compustar 2wfmas into 95 auto taurus sho

i have a lot of questions, once i get started on this install that i hope you guys here can help me with. i have a wiring diagram for my car, and wiring instructions for the cm3000 that i found on here.

first off, i was looking in the ignition wire harness, and for my compustar it says hook the red 12v constant up to the 12 v constant(which according to the wiring diagram is a yellow wire on the harness). my question is, there is 6 yellow wires in the harness, all exactly the same, how do i know which one to hook up to w/o a multimeter? or does it matter?

second, the parking light (+), the diagram says its a brown wire on the headlight switch harness, i couldn't find a brown wire though. where to look? thanks alot guys.

its all hooked up and working except for the trunk trigger and trunk release.

for the trunk release, it says to tap the purple / YELLOW (+) from behind the dash, but the compustar sends a 200ma(-) pulse for the trunk release. how do i hook this up? w/ relays?
