|February 16, 2010 - Nice work, GM!|
The connectors for the ECU (actually, I think the term is PCM but I'm going to stick with my usual) might be huge, but after you pop off a couple of plastic covers I discovered that they're ridiculously easy to modify. Simply lift the wire terminal of choice upward a bit and lift the tap on top a bit further, then push. The wire slides right out. I used a dental pick when I was dealing with a single terminal in the middle of a bunch of others, but it's possible to do this with your bare hands.
A couple of minutes later, I had removed the wires I didn't want. If I decide to put them back later, they just push in.
