No worries, just trying to help. Standard 30 amp Automotive relay. Like this, https://www.amazon.com/Bosch-Automo...t=&hvlocphy=9004386&hvtargid=pla-605056471182 You can get them in any parts store. You don't have to order it from Amazon.
Here is advice from someone who has a lot of experience with Buick's and the FiTech or Sniper style systems. Forget using the Holley timing control. Run the MSD for timing. You already have the MSD set up and tuned for this motor. Drop a set of points in if you do not want to get an MSD distributor. You will never wear out the points unless the thing gets driven thousands of miles per year. Setting up the Sniper will be much easier.
