Hey, I saw a couple DIYs for this but both were V1's and neither was into the fuse box. Before I start, this DIY is essentially written by Josh49, who walked me through it step by step.

Reference this thread: http://www.e90post.com/forums/showth...e+box+hardwire

So you have your Escort, your hardwire cable (which comes with a little tap clamp), and your mini-fuse tap (see here: http://www.anythinggps.com/browsepro...-100-Pack.HTML)

We are going to hardwire into the fuse box and use the homelink/pdc fuse so the detector goes off/on when you start the car. It also has the protection of it's own fuse, which I like.

First, use the little blue clamp that came with the hardwire cable to clamp it to the fuse tap, like this:



Now open the glovebox and remove the fuse box cover.

Take out fuse #28 and connect it to the fuse tap (in the pic above you can see my fuse #28 is already connected to the tap), then insert the tap into the fuse:



Now ground the wire using the ground. I unscrewed the hex bolt shown and just grounded using that, the ground should screw right on to the bolt, then the bolt back into the metal:



Before you go any further remember to make sure it works. Plug in the escort and turn the car on, it should fire right up. Mine didn't, and I got all pissed and started checking connections and stuff, turns out my fuse tap was in upside down, so if yours doesn't work first time flip the fuse tap. For me it was the counter-intuitive direction (wire facing up).

Wire running time. I have the hardwire cable with the little remote mute box, some will have this some won't. If you have it follow this next step, if not skip it.

I ran the box and both wires through the glovebox arm, then like this:



Use a flathead screwdriver to push it into the opening so it stays, you'll have two wires at this point.

Now, run the telephone wire back from the remote box back through the glovebox and out the other side (for those of you without the remove box just run it out this side to start):



Run the wire up the side of the dash, use a plastic tool like a small spatula or a butter knife to lightly pull up the rubber gasket and put the wire underneath, it isn't hard. Keep running it under the gasket all the way up, like this:



When you get to the top of the A-pillar run the wire behind the a-pillar (as shown) and then under the headliner (it tucks right in under the headliner neat the window). You can tuck any excess into the headliner, you'll only need ~4 inches showing or less.



That's it. Use the supplied velcro to hold down the remote box, like this:
