I cannot believe that Holley, after charging me so much for the Pro Dash, does not even include the little pins to terminate wires needed to install BASICS LIKE A FUEL GAUGE, TURN SIGNALS, ETC....Whoever writes the instructions, both in print and the digital ones included on the thumb drive do not make it clear how to do such things... You really do need to spend a lot of time watching others on YOu T videos on how to install this thing. Come on Holley. you can do better.

Love the Pro dash. But this is way overpriced for what it does. It also doesn't come with everything you need to use the I/O's. You will still need to purchase connector pins and crimp tool to use the I/O's.
