Where do most of you mount the ignition box and the coil (pictures please).

Thank you in advance.

I ended up mounting both on the passenger foot box. This picture was taken while I was wiring everything up and it's much tidier now.

Papa, can you post a closeup pic of your wiper motor wiring connections? I'm at that stage and I need to be sure I'm getting it right. I've had parking problems and am looking for a solution.

This is what I did. Coil in front of the passenger footbox and I used nutcerts on the CDI box mounted to the firewall.

I'm surprised you don't have issues? I would think the coil shouldn't be that close to the ignition box nor the coil wire passing over it.

My tuner rerouted the coil wire over to the back side of the engine and along the valve cover to the distributor due to interference with the O2 sensor. Other than that, no issues.

You can see the wires in the picture above. Black on the top-center, brown upper-left, yellow upper right, green lower left, pink+white lower right as you look at the plug on the motor. This matches the diagram in the wiper install sheet. Are you using the FFR switch or something else?

Right where I plan on putting it. Thanks John.

Nice clean installation. I used the supplied coil driver instead of the ignition box for my setup. The ignition box had received bad reviews at the time I was installing the Sniper. Multiple posts on other forums stated it was prone to failure. Hopefully Holley has fixed that by now. My initial installation had a bad RF interference issue. Holley tech support had me move the coil driver to the driver’s side footbox top and the coil to the left F panel as part of the solution.

A couple of things to consider. Access to that area is a little restricted once the body is on. That and, depending on your choice of air cleaner, you may get a RF issue with that location.
You can see in the attached picture that I also had to shield the distributor to protect against RF because of my oval air cleaner.
