Battery relocation

Hello, hope everyone is doing great!

After reading some of the posts here, decided to relocate the battery to the trunk in my 1972 Dart. I ordered the Summit Racing SUM-G1230-K-Summit Racing Premium Battery Relocation Kit.

In one post, I read that member "crackedback" wrote: I dont like having the starter cable hot, except when starting the engine. I would run starter of a Ford relay.

Any Ford relay will work? Can I get it from Amazon, Ford dealer? I have been reading multiple posts to get an idea how to do it properly. Trying to find posts with pictures showing the Ford relay connection to starter.

Really appreciate your advice, guidance on this procedure. Thank you for your time and help.
