Default LED replacement bulbs for 03 Ram

I have a 2003 Dodge Ram 1500 and want to remove the rear 3157 bulbs from the rear and want to replace them with LED bulbs. I have the resistor to attach to the wires, but I do not know witch wires they go to. Can someone help?

Thanks,

Ok, for anyone who wants to add LED replacement bulbs to our rams, and they have a 02-06 ram with the circut boards on the tails, most charts will tell you to use a 3057 bulb, more commonly known as a 3157, well what most wont know is that there are whats called a 3157 SRCK bulb, so what that means that the 2 bulb types share plug sockets but the wiring in the sockets are different, now why is this little bit of information important, because the use of a regular 3157 LED bulb can cause a few different things to happen, some as simple as the bulb just not working, but also a bulb i tested actually caused a short in the system, which had it been hooked up to the truck, it would have shorted out the FCM, and we all know the FCM is not something to mess with on our truck, and its not a cheap part to mess up on a regular basis, so in short if you are going to replace the bulbs in your tails with LED bulbs BE VERY CAREFULL, if you get the wrong one it can be a costly mistake.

now this only applies to the TAIL LIGHT CIRCUT BOARDS, of an 02-06 ram, no where else is this a concern to our trucks, if you have an 07-up, you dont even need to be reading this



This is info from a DT thread that talks about this. So if you are using a regular 3157, that could be a problem.

Thumbs down I have the LEDs with the four wires

I know in order to have them work correctly I have to install the resistors so it will be able to pull the load.

Thanks,
Brian

jk360,

I got the bulbs off ebay. I did my front turn signals and had to use the resistor to make them flash. The only thing is on the turn signal there are three wires and a diagram that shows you where to hook it to. The tail light has four and they are different colors on both sides.
