Here is a pic of the wiring harness you will need and that Luke ([email protected]) does a great job building:
The Brown Arrow (bottom left of pic) shows you where the harness plugs into the HSWM (which you'll tuck/zip-tie under the dash just above the OBD port).
The Blue Circle shows you a connector that isn't required for our Expy's...this wiring harness is for an F-150 and this connector goes to an OBD Test Port, which we don't have (or I can't find) on our Expy's. Mention to Luke this wire harness is for an Expedition and he'll leave this connector off and will mark which wire goes to the MS CAN + or - connections. I spliced into the OBD Port (under dash-just above driver's right knee/leg) wire harness to access the MS CAN connections.
The Yellow Box shows the connections that go up the steering column to back side of the clockspring...the connector plugs into the clockspring, and the 2 wires are marked (pins 2 & 3) for where to insert the pins into the back of the other connector on the clockspring.
The Red Polygon is for connecting to a 12v source that is on in the Run mode...you should only tap into a source that is powered when the ignition is to the On position. I tapped into a connector on the BCM using a quick splice connector.
This may sound confusing now, but I will post pics for each step of where to connect the wiring harness...easy to do.
The entire process of me disconnecting the battery (then waiting 15 minutes), removing the old AirBag, old steering wheel, and old clockspring, then installing the harness, HSW clockspring, HSW, HSWM, and new AirBag, then connecting the battery, took less than 3 hours...and that's with me taking my time and photos to document the process...a reasonable person should be able to accomplish the HSW install in 2 hours or so.
