Lmc parts... Trying to connect new rear wiring harness to new tail light housing.
One side seems to connect ok, the other no luck, when I insert bulb the connector pops off housing!

Is the spring compressing corectly?

The spring seems to be compressing fine. There’s just not a lot of surface for plastic prongs to grab onto

Send it back for another one...

Poorly made aftermarket light housings are the problem.
They have more of a rounded rim where the plastic harness clips onto.
You may be able to file your part down some to allow more of a bite?

Not the best stock photo, but you can see the difference on some OE tail light housings.
Good luck

I had the same problem with LMC taillight housings. Left one fit no problem, right kept popping out the wire harness when plugged in the bulb. I finally got it to hold, I’m sure it will pop off again and I plan on using firedemon’s idea and shrink tube it.

Try a tie wrap around it to keep it in place.

Tommyups · 12-08-2018, 02:34 PM

Thanks for all the advice, I ordered some of the shrink tubing going to give that a try.
This is my first c 10 I’m just wondering if all the aftermarket parts need tweaking

Some do. There are better places to buy parts than LMC. But you are better off getting new old stock or good used parts. To me hunting down good used parts is the most rewarding part of the process. Avoid aftermarket when you can. Good luck with your truck!!

It sucks not being able to hear! LWB trucks rule, if you don't think so measure your SWB! After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
