Wiring harness

[beef56]

This is a photo of the wiring that is on the Spyder we bought. I am attempting to connect to a trailer we bought. I would like to use this rather than install a new one. I purchased an automotive plug but it is just a little too large. Any ideas what type this might be? ThanksResized_20170312_102057.jpg

I hope whoever wired it followed the standard wiring / pin assignments!
If it were me I would use a meter and make sure.
