HELP! OEM LED headlight conversion troubles

[Miguel]

Help, I did the OEM LED headlight conversion on my 2019 Ram 1500 Big horn and with the retro shop wiring harness and the lights work great but after I finish the conversion, when I try to start my truck it flags a slew of warnings and caution messages (see pictures) and it won't start and I can't figure out what I did wrong, I tried disconnecting the battery for 30 minutes (twice) all the fuses are good and any ideas?

Let it sit couple hours or over night after hooking back up and see if it goes away. Mine did that when I unhooked everything a few months ago. I freaked. Left everything hooked up went to bed and by morning everything was back to normal.

Not to highjack your thread but, mine through out almost the same warnings a couple weeks ago. I thought it might be the Pulsar causing it. I removed it and the engine light was still on. Took it to the dealer and it was a small evap. leak near the fuel filler neck. They fixed it and I got it back home and installed the Pulsar again on Monday and low and behold today I got all those warnings again! They turned off but the engine light stayed on again! I guess I'll remove the Pulsar unit again and take it back to the dealer. I hope its not the Pulsar.

Sounds like you didn’t install the fuse back into the new lead. I made the same mistake. It seems like the truck is “on” but there’s no ignition. You HAVE to use both fuses.
