I have the Ron Francis wiring harness in my Cobra. Couldn't be more pleased with their support, knowledge, and the quality of the kit. My fuse panel was installed in the forward part of the passenger footwell and I wouldn't recommend that. I bought the car after the wiring was done and that was one decision I wish was left to me. Regardless, Ron Francis is a great company to deal with since I've had to get their support and I didn't even buy the kit from them. They've been great.
They have an option called Select-a-circuit that allows you to choose between circuit powered by the ignition switch or not. Very cool.
Go to their website:
