I am new to the forum and was wondering if any of you guys have put aftermarket gauges on your trucks. I have ordered a transmission temp., an oil pressure and a voltmeter gauge. Can anyone give me any advise for the installation. I want to mount the transmission senor on one of the cooler lines and not on the pan. Also how do you install the oil pressure and voltmeter gauges. I do some minor towing (3000-4000lbs) and would like to monitor everything. Thanks.
