You've probably already done the job, but just a headsup for everyone to be careful unplugging bay electrical connectors. All of my '96 bay plastic is suffering from embrittlement. I'm always gentle with harness connectors, but despite that my TPS connector shattered the last time I had to unplug it. It still hangs on via friction and the rubber insulator barely makes contact, but there's no retention clip anymore. The same can happen to the IAC and other bay connectors, and replacement connectors are not cheap.
