street / strip wiring questions

[mcv]

Iam at the point now of getting ready to add a holley sniper stealth system to the car. The car runs and drives now. The car is going to be mostly street with a few passes now and then. What is y'alls opinion on wiring this thing ?All the original wiring is there, but has been spliced into and mouse chewed and fixed over the years. Should I buy a universal 21 circuit wiring harness, or race car wire with individual switches..... or run a secondary fuse box to run line lock/fan/ etc.? Electrical was my dads expertise, so I never had to wire anything..... now that he is gone ,looks like Iam gonna get an education. Any advice would be appreciated.

car is a 1967 plymouth belvedere.... manual steering/ manual brake car
400bb ( for now) ,edelbrock e street 75cc heads tm-6 intake ,hughes cam, msd ignition, 727 reverse manual valvebody, 3500 stall
mini tubbed ,narrowed 8.75 3.91 suregrip/ also have a 4.30 spool center section to swap back and forth.
ladder bar rear suspension with coilovers.
full cage
body is wavy, lift off glass hood
I am just trying to get it out and enjoy this thing

I don't think you will need a 21 circuit harness for your options on that car. If you are going to use the Holley ignition system there are only a few connections.
I have a Speedway basic streetrod harness that I bought for my 64 Savoy and it looks like it would work for your application as well.
I don't know where you are in Ohio but you could look at it if you wanted to.

I've used American Autowire "hot rod" type harnesses for LS-FJ40 swaps, and their specific harness for a '53 F250, updated to 12V neg ground & alternator.
Great results on all of them, very little tweaking (I'm fussy).

I had a guy offer me a brand new 21 circuit cheap......I will look up the street rod harness. I am keeping the msd 6al box/distributer/coil. I am just going to run the sniper fuel injection.

Looks like street rod harnesses are what I am looking for... Thanks
