I used the ARC kit and I have to say it was very easy and an extremely clean installation. All the circuits are fused with relays. Its a complete kit, affordable and easy to install.

Mount relays close to their intended device. Fuel pump, fan, water pump, msd etc. Mount your switch panel, (and fuse block) if it's not integrated. I like using the insulated power studs from Speedway as a central power source on the fire wall from the battery. A second stud on a mounting plate for the MSD and junction block works well. Each relay get a ground and 12 volt battery feed. Use the battery at the rear for the fuel pump relalay. The alternator output stud for the fan and water pump relays. The firewall power stud can feed the insulated stud on the MSD mounting plate.. Then each relay feeds from its control switch. The switches can be battery powered (fans, waterpump) or ignition switch powered ( msd, fuel pump etc. I'll take a few pics of my diagrams for you later today. Once all the components are mounted. It's just a matter of bringing the wire back from the component to the MSD/dash mounting plate terminal block. Then from the plate to the switch panel. You can see the insulted stud at the right upper corner of the pic along with the terminal strip. More pics to come. Doug

I used to do them all myself as well. I have since gone to buying kits to wire them up, makes for a nice tidy package and speeds things up. I have used K&R, ARC, Painless, Smartwire and Speedwire. I now prefer Speedwire stuff, but its not for the faint of wallet for sure. I like having a main board where everything land with LED's to tell me if there is an issue. Also prefer the serial cables to the switch panel provided.

ARC is what i have, it makes it really easy to do it neatly . Works really well I was leaning to one of these and eliminate the stock key start. Not sure how to bypass and use the ARC panel start switch.

Not sure how to bypass and use the ARC panel start switch. i still use the stock starter relay. Just use the ARC panel to provide 12v to the relay on the small stud.

there is some really good info on YouTube about automotive wiring ..... there is also some "bad" info, Have to be careful , but there is some good for sure.

I wanted my starter relay in the trunk, and because the stock style relay had been less than reliable for me I changed to a ford style. I got a relay from a Jeep CJ5 with an automatic transmission. It is the Ford Style relay but requires a ground for the neutral safety switch like stock. It has worked good and I like having that cable only powered when I push the starter button.

The all in one boards, ribbon cables, kits, printed circuit panels, etc. are nice until something in them fails. How many people carry spares?
I still like to source my components, build my own system for the requirements of the car in question. And be able to carry spare parts and easily identify and fix any issue at the track.
I have specific ways of organizing and putting a system together. No kit really fits what I like to do. So why buy it and only use half of it?

If the results don't match the theory, change the theory.

I have to re-do my 70 Cuda street/strip car, and I have been looking at the Smart Wire....Expensive, but it does a lot. Thoughts?

Valid point, and I don't trust the ribbon cables when it comes to stuff like that. My relay panel has extra circuits so in the event of a failure I can move two wires and be back in business. Being a street car I try to built in some redundancy and ease of service into the package and that works out well for the track also. Changing an MSD box on the side of the highway makes you look at your wiring differently lol.

If it’s a basic race car this is fairly simple . Draw it out . Look it over , keep it simple . As dvw said locate relays near the heavy loads and keep a spare relay in the race tool box . Label things as it makes troubleshooting under pressure easier . Tag wires with a label, and label fuses and relays

Thanks Doug for the wiring diagrams I've been drawing it out looks real similar to mine question what's the ign. wire with the switch looping back to the battery peg on the relay for? Is that required because it a push button start

Is that required because it a push button start The yellow wire with the switch is for bumping the motor for valve lash. It is mounted on the engine side of the firewall. Doug

I would highly recommend adding a bump button like that, I am glad I did!
