My brother is having issues with his temperture guage as it pegs on start up. At the same time it kills the odometer-speedometer. While going thru trying to locate the ECT sensor which we finally found on back of engine. 2.5 L I believe is what he has. Anyway for about 15 minutes we got it all working again, so leads me to believe what ever wire is causing it is shorting out somewhere. If you take the plug off the ECT it does not peg but the odometer/speed still doesn't work. Can anyone point me in the right direction of the wires that could effect these items. Thanks.
