I ordered the LMC HD light harness. It took 3 weeks to deliver after paying way too much for shipping. When it arrived I noticed that the plug that plugs into the existing wiring was a three prong spade plug. My truck has a 4 prong plug that is a post style with 2 female and two male. I contacted them days ago with still no response. I know I could have wired my own harness and I know I can still slice the original plug minus the ground into the system. But the lack of response and the wrong plug and play pisses me off.

 

Interesting... it was plug n play on my 73/74 4x4. No problem at all although I wish their harness were at least 12 inches longer.

 

X2 on HIO's comment for my 78.

 

X3 though my 74 is 2wd...

 

...X4 on my '70 2WD.

 

It plugs into one of the head light plugs at the lamp, not the inner fender harness.

 

Yeah man I think you're trying to plug it into the wrong connector.

 

When all else fails, read the instructions.... or at least review the diagram!

 

Thanks Pat67. That was what I was doing. I thought the harness replaced all the wiring. LOL And yes I didn't read the instructions all I saw was a bunch of Korean writing and blew it off. Learn something new everyday. Thanks guys.
