Need part

I recently put a new head unit into my 2002 camry SE. By accident I cut the wrong wire, and now the Thermostat, Clock, and seat belt warnings do not work on my car. Every person I've talked to says I need a new in dash wiring harness. I really only need the plug that cost 50 cents to make. The plug goes into the back of the clock, thermostat, and seat belt indicator. The cheapest price I've gotten so far on the kit is 300 bucks. If anyone has the part or knows where I can get just the plug or maybe somewhere I can get the kit cheaper then that please let me know.

I'd check with a salvage yard /u-pull-it place, whatever they call them in your area. also, didja check e-bay?
I 've found parts there for pretty good deals1


HTH,
