tizfun Posted February 6, 2011 Report Share Posted February 6, 2011 (edited) Hey all, It's been a while since I've been on here but here I am hoping someone can help me figure this out. My Xterra has the 7 pin trailer connector and I'm hooking up my 4 pin trailer. I have everything in place, but I'm not getting any left brake or left turn signal.. Everything else works great. I've tried it with my dads truck who has just a 4 pin connector and all the lights work normally.. So I'm thinking it has to be my truck.. but where ?? This is a direct install from Nissan wiring and all. So where can I look and start to test.. Any help would be very very appreciated. Thanks, Tiz Edited February 6, 2011 by tizfun Link to comment Share on other sites More sharing options...

Here's a diagram of the 7 pin wiring. Trouble shooting is as easy as testing the pins with a test light. 7 pin to 4 pin adapter. Link to comment Share on other sites More sharing options...
Roy Posted February 6, 2011 Report Share Posted February 6, 2011 Tiz, I don't think it's even worth the effort. I have 7 pins off the truck and 4 pins to the trailer. Had a problem last year, went to a trailer dude, he fixed it up, took him less that 10 minutes, charged me nothing. I asked what it was so I'd know for the next time and in my case, all it was was that my truck has a different wiring sequence to the trailer.

archer379 Posted February 6, 2011 Report Share Posted February 6, 2011 if your using the adaptor from 7 down to 4 try ending the pins in or out a little sometimes they don't make a good contact. Link to comment Share on other sites More sharing options...
