Fitting aftermarket harness to old

[Squarebodysimons]

I got a aftermarket harness for my 79 and Im having a hell of a time trying to figure out how to mate these two so I can reuse my factory gauges would anyone happen to have the answer to this?

Hmm... What are you looking to know specifically? I did find a gauge cluster pinout for you if that's what you needed. Your harness should have the cluster portion defined so you can match those colors to the factory pinout.

I appreciate the reply I was hoping someone knew the color code to it cause I had found that pinout my self and my temp gauge was working as my voltmeter and the left turn blinker kept flickering sorry I'm new to all of this

Well, your colors are there, too. I saw a yellow wire in there somewhere, but the rest of it looks like it matches.
