Have a 2003 Dodge 2500 that I am installing the Banks six-gun tuner/speed loader in. I've installed the pyrometer and boost gauges, and also picked up a Banks trans temp gauge. All three are in the column pod and look great. PROBLEM is the temp gauge suggests placing the sending unit in a plug on the passenger side near the servo. I found four plugs on my passenger side and upon checking my build sheet found I have the 48 RE (directions are for the 47). Can anyone tell me where to tap into the 48RE for now (will probably go with something in line later). Thanks.
