Help! Trailer brake controller not working... good shop in Salem, NH/Lowell MA area?

I have been trying to go to the Vermont Morgan Heritage Festival, always held the first weekend in July, every year since 2008 when I bought my horse. This year, everything finally has come together… but we just went to hook up the trailer, and the brake controller (Tekonsha brand) is flashing red saying “No Trailer Attached.” DH has reached the limits of what he can test out at home. If we can get this fixed tomorrow, we can still go to the show.

The Tekonsha website lists the following local places as possibly able to do “on the spot” repairs. If anyone has recommendations, please let me know!

JJM Auto and Fleet Services, Salem, NH (has good reviews)
Welch Welding, Chelmsford, MA
Forrest Marine and RV Center, Tyngsboro, MA

I have used Welch Welding before. You could also try an RV repair place too.

All fixed. Just had a bad connection. JJM checked everything out; they were SO nice to me on the phone this morning and DH liked them too.

I used Yered Trailers in Medfield, MA. George is really good and VERY thorough! I hope I can find as good a shop here in Texas too.
