Gen5diy DRL Harness Problem

[jetlife]

I installed a Gen5diy drl harness (p/n 250450) to keep the drl's on with the turn signals. It is installed correctly per their instructions, but the drl still cuts off when the turn signal is on. The truck functions as if the harness isn't even there. The instructions say to plug into the #50 underhood fusebox fuse. This shows as the oxygen sensor a fuse on my 2016 Z71 LTZ L83.

 

I've tried two other 15A fuse locations, #46 (oxy sen b) and #54 (frt wash) with the same results. 

 

I noticed in the install instructions that fuse #70 (ecm) is a little larger than on my fuse block but the layout of everything else looks the same.

 

Has anyone else used this harness and had it function correctly?

I have one on my 2017 and it works great.  Have you tried to contact them?

Yes, I have. They had me check if the wiring in the harness was routed correctly. Is your #50 fuse the oxygen sensor A?

Not sure I will try to look tomorrow. Did you check to make sure your fuse is good?

All fuses are good.
