OPT7 LED BAR HELP!!!

I am installing an opt7 led lightbar I was gonna hardwire everything. I plug the 4 pin adapter into my trailer 4 pin plug and immediately only thing i get is running lights, no turn signals! I have never used my 4 pin plug before this. I checked the tow fuse under the hood and it was not blown. To make sure it was not the lightbar malfunctioningi plugged it into my other trucks 4 pin connector and it worked perfect. Does anyone know what I should try or if there is another fuse I am missing?

I dont understand why you pointed me back to my first thread...i started this one because I asked the question the wrong way on my other thread

 

I think you're right. I think the "computer" measures a few things resistance, grounds, powers, if it's under / above a certain threshold / criteria, it'll do different things, hyper flash vs not work at all etc.

 

No they do not work when connected only the running lights..makes no since, I can hook the led bar up to my other truck and no issues at all

 

I was gonna use this curt t connector it would have been straight plug and play but turn signals are not working..https://www.curtmfg.com/part/55384

 

I used the Curt 55384 on the 7-pin with absolutely no problems
