Good product, fair price.
Used it on a 37 Buick Coupe. Easy to install and worked pretty well. Brake light wiring was a little confusing but in the end we got it working.

You get a great quality harness
This item is impressive for the price. You get a great quality harness, clearly marked wires, and quality connections. What you don't get are instructions. So, google speedway 20 circuit harness...use their instructions. Almost seems like ez makes the harness for speedway. Who knows. But, if you can wire, you can figure this out. If you can't wire, buy it and find someone who can. This is a serious value kit. The gauges are very appropriate for the application, I was very pleased.

3rd one
Third one I have bought to install in street rods. Need a basic understanding on automotive wiring and it is a breeze. Had a small issue with my start up last spring on our 35 Hudson. Emailed support and got an immediate email back asking me to call. He diagnosed a dead short in my alternator. Bam, down the road we went.

Great Product
These EZ Wire kits are my go to wiring harness kits. This is my sixth one. The instructions could be better but if you pay attention you shouldn’t have any trouble. Of course the wires are all labeled every six or so inches. This kit hits the sweet spot between price and quality.

Good price, works well. Second one I have used.
Like the harness. Instructions poor, fortunately I have experience at wiring, would be hard for first timers.

Wouldn't recommend it
Some part of the wiring diagram are great. Others suck. Has some sort of short where the electronic fuel pump is always on. Turn signals only work as hazards. One headlight works other is only high beam. After doing research to find my problems found that these are common issues with this kit.
