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?

Does it do more than you need? If so get what you need to save on the costs and excess wiring

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.

Man,
You never cease to amaze me !!!!!!!!!

Do you sleep????

LOL

I agree with this .
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

i couldn't find a smart wire site.
do you have a link ? TIA !

Probably because they were bought by Holley:

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

The yellow wire with the switch is for bumping the motor for valve lash. It is mounted on the engine side of the firewall.

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

Talk about sanitary.....I'm impressed!!

SmartWire is what I have used for years, it allows you to do things that are not possible with the ordinary analog wiring. The only thing that I would say about this system is if you are computer literate you'll be fine, if not get someone that knows computers and programming to set it up for you. SmartWire is a typical PDM (Power Distribution Module) that is designed for racing. It has one power input from the battery and can be controlled by any number of switches you desire (both analog and programmed). The number of loads is up to you... all you need to do is program them.
