Simple Coil Wiring Question
We are having trouble figuring out how to do the coil wiring. From the harness
From main trunk:
Orange - Coil or EFI
Blue - EFI Crank
Grey - Speed Sensor
Green - Speed Sensor
From the Sending Units Harness:
Purple - Coil - Tach
We've done as much research as we can think of and have no idea what should be connected to what.
Any help would be appreciated.

Do you have a carb or EFI setup in your build? There is differences on type of EFI vs carb as well.
Orange goes to + side of coil.
Blue goes to ECM for crank signal if Carb you do not need it.
Gray and green go to your speed sensor on you transmission for the speedo to read MPH. If you have GPS speedo not needed.
Purple in engine compartment goes to -side of coil
Purple in dash goes to tach.
The wiring diagram is fairly simple IMO. Maybe you know someone close by that reads wiring diagrams to help you out. If not ask away any more questions you have.

What distributor and are you using an ignition box? That also makes a difference.
