I upgrade the connector on my trailer from a 4 pin to a 7 blade connector. The 4 pin is easily damaged and hard to connect. The 7 blade is more durable and easier connect. 7 blade connector-www.amazon.com...
I have got to say , you saved my bacon with your diagram of where the indicators go, the ground and the tail lights. None of the other you tube channels were any help. WELL DONE
Roger, I did this for my boat trailer b/c I got tired of the 4 pin connector always shorting out at the slightest wiggle or bump. Once I replaced with a 7 blade connector, I had no more issues. Well, I see you have all your lights working as you hoped. Good job. Enjoyed the video; full-watch. 👍🏽🙂
You should use o-ring terminals which are SEALED. Otherwise your wire will oxidize and go black after just a few months of moisture/environment exposure - which would lead to all kinds of issues down the road. Never leave wire exposed - use crimp heat shrink connectors.
Hello! Thank you for this video. I have a trailer that has a 4 way connector. I purchased the autosonic 7 way trailer plug with junction box. How were you able to determine which wire controls which function by testing it with the meter? I unfortunately cut off the flat plug already.
@@obdrumguard You can also figure out which one is the ground. Then you can touch the ground and another wire on a battery at a time to figure out what each wire does.
Commenting from Nebraska. Can anyone help me out with a similar project? My carry-on mesh trailer has a 4 pin connector with 5 wires...white, 2 browns, yellow/brown and green. I'm not sure what color wires are on the front clearance lights but the left taillight has a yellow/brown wires and the right taillight has green/brown wires. Other than figuring out the white wire is ground, what are the other wires and what terminals do they go to on the 7 pin connector?
I mentioned that they may use color wires. A new trailer may no use the standard colors. Figure out which one is your ground. Then you can touch it and a wire on a battery to figure out what each does.
