: No-cut wiring of new headunit to EX's sub connector

Tools:
Wire cutter
Wire stripper

Supplies:
A discarded stereo RCA cable (I used one with a known-bad right channel)
A stereo male to mono female RCA Y-cable
One standard resistor (any value) with uncut legs
Two red (18-22 ga) bullet connector plugs (male)
Two red (18-22 ga) bullet connector socket (female)
electrical tape

Take one of the channels of the RCA cable and separate it from the other by peeling it off. Cut it approximately 5" from one end. Strip the outer jacket and about twist the exposed shield semi-tightly - about 1". Cut the twisted shield to about 3/4". Strip 1/2" of the inner shield and twist the exposed 1/2" of the inner signal line.

Crimp both bits of the RCA cable to the male bullet connectors in such a way that they can be placed side-to-side and have the connectors approximately lined up.

Take the resistor and remove the tape from the ends if it is taped (mine came in a bulk pack taped in a line with dozens of ther resistors). Crimp socket (female) bullet connectors to each end. Then, cut the leads close to the resistor housing. Voila, two semi-rigid pins.

Attach bullet connector side of the pins to the bullet connectors of the RCA cable. Tape the two double bullet connectors next to eachother using electrical tape so that the pins are sticking out in parallel to eachother about 3/8" or so apart (to match the sub connector spacing). You can also tape further down the RCA cable a bit to cover the crimp points and for stability.

And you're done: you have two pins, about the right space apart. Connect the male RCA end to the female end of the Y-cable. With an VOM, note which pin goes to the shield and which to the center conductor (you've probably lost track at this point).

Now, the sub connector expects fatter pins than the resistor leads, but you *can* wedge the resistor leads into the spaces right *above* the standard pin holes on the connector. This may be the space used to release the OEM pins from the connector using a small flathead screwdriver. So, in addition to taping your homegrown connector to the OEM plug, you should probably tape up all around it as well, just to encourage the OEM pins not to fall out. :)

Oh yeah, don't forget to plug the other end of the Y-cable into your headunit's non-fading or sub outs...
