Question:
I need clarification on Tekonsha 118270. Does it fit a 2014 Buick Enclave without factory tow package? I tried CURT 56245 but no success. It had no power at the 4-flat plug after plugging it into the factory connection behind the rear quarter panel and ing the fuses and relays so I thought Id try this T-One connector. Thanks.

Thanks for your question, Cameron.
Yes, the Tekonsha part # 118270 is a confirmed fit for your 2014 Buick Enclave if equipped without a tow package. It's possible that one of the relays or fuses are defective causing the factory plug to not get the power it needs to work. It's not common at all for that to happen but it can. I'd double check those. If you do decide to replace them and you're still not getting power, it could mean that there could be some sort of damage to the plug on the vehicle and it's not working.
I know it's not the greatest of news but at least it's a start with what you have and to go from there.
