Installing MAF Calibrator; any advice?

[eltaco]

I've received my URD MAF Calibrator, and just took a look at the wiring. I'm curious if there are any how-to's out there that I've missed or any installation advice for me. I've worked with wires a few times before, but I want to have a pretty clean finish when I'm completed. How are all of you splicing into the wiring? What tools are you using? Any other information?
