Oil pressure gauge power/Autopower Harness bar(Two questions in one!)

[Stangcobra1122]

Hey everyone, got two questions.
First: I'm installing my autometer oil pressure gauge, and need to know how I can power it, I heard something about fuses 35 and 37, and bought an add a fuse, but the issue is it will not slide all the way in and will fall out if I drive, its the right size but I guess needs to be taped in. So should I just tape it into fuse 35 or fuse 37.
Second question: I've got an autopower 4pt cage and want to add a harness bar and harnesses, where can I buy the harness bar from, as I have searched all over, or will any old harness bar work.
Thanks

Take a test light/multimeter and find a key on power source.

Find a local circle track shop and have them fab one for you. You're in NC should be tons of them around!!!

I dont have either of those and I'm trying to keep costs down so...
Same basic idea here, if there is a version available online for less I'm all over it, getting things fabbed up costs a lot lol
