I finally solved the airbag switch problem this weekend. I installed a passenger side airbag switch in my new red 5-sp Insight, 03-781. (See also my post on mods. in the Modifications Forum). I wired in a switch I purchased from a company called AOI Electrical, Inc. It is their US-1 passenger switch for $199. The installation took a few hours, but was not difficult. The hardest part was getting enough wire slack to splice in the switch harness wiring. I removed the glove box and the trim piece around the radio to gain access. Followed the instuctions and wiring diagram exactly. I spliced into the positive (yellow) wire of the power point for power and used a nearby bolt under the airbag plug as a ground. Cable tied all the wiring (with strain relief--an aircraft wiring trick) down so no rattles or broken wires later. Works great. Took my 4 year old (in a booster seat) for a ride right after. He loved his first ride in "Daddy's new red car"!
