I am using MSD 6AL make sure it does not have the rev limit display active.. or it will put tons of fuel in on ignition on

I am wired aftermarket.. I use a main power line right from the battery.. Tried one at a junction box and did not get enough power supply.

I think any throttle linkage will hook up just like a carb.

O2 Sensor.. I have long tube headers and my hook up is about 3 inches after the exit.

I ran a 1/4 inch return line to the tank.. no issues, instructions should help you out.
