I just went over a tone of threads and my understanding thus far is that my particular Jeep (07-on) have the 3157-CK bulb sockets in the rear.
No mention on what wiring they have in the front blinkers/parking bulbs though.
I just want to let everyone know on what I did and how it seemed to work only about half way though
Not knowing the rear needed 3157-CK's I got the regulars. After I went through the fuses like everyone else, read stuff on here and there and rewired the bulbs. The cheap stuff I got off of ebay was easy enough to rewire the leads and now it seems to be correct.
Weird stuff goes on...(Let me mention I have no resistors in yet) Rear driver side works perfectly, passenger side, not so much. Having this single bulb setup on my 07, it needs to do 3 functions as we all know (brake, blink, park).
The passenger side like I said works ok as long as the park light is OFF. If I turn it on, it flickers. Now, if I pop the LED's out and put my incandescents back in, it's all perfect.
I went ahead and ordered the 50W / 6Ohm resistors and I'd be splicing them in parallel with the blinker wire and ground wire for the rears.
Curious enough, there are different blinker relays for each lamp. Meaning you have 4 separate fuses / relays for each front, rear, left, right.
Based on what I read, the front does need resistors if you switch to LED's on the blinker/park lights. Most people suggest the 3 Ohm version. Can anyone confirm or deny that for the front?
Also, does anyone know for sure if the front uses the 3157-CK or the regular 3157 as far as the wiring goes? I am particularly interested in 2007 WK.
Any responses are more than welcome.
