70 Cuda starter relay wiring

[rb70]

My harness has been hacked to death, does anyone have a drawing or better yet pics of the wiring from the firewall to the relay?

I have a yellow wire coming throuh the firewall to the relay and from what I can tell from a wiring diagram. It should be a red wire with a fusible link going to the relay from the harness.

You should have both yellow & red-w/fusible link ....this pic is from my '73 but should work for a '70

Thanks, that was exactly what I needed.

sorry to kick up an old post but where does the ground on the relay come from. I put new harnesses in my 70 challenger but dont see this plug anywhere. 440 auto.

The ground comes from being in contact with the body of the car.

Sorry meant the wire labeled ground from interloc trans. That point i don't have a connector. I put new harnesses in my car and am not getting power at the ignition switch.

Just checked my car. On mine it's a brown wire with a yellow tracer that comes from the NSS harness. It's the plug on the bottom left of the bulkhead connector looking at the firewall from the front.

There is a separate harness for the interlock, one if automatic, a different one if manual.

Thanks guys just ordered that harness the other day. That explains quite a bit for me.

The ground for the relay to operate is from the transmission if auto, clutch switch if manual.

I'm going to go out on a limb here but I believe not many 4 speed folks have this hooked up.

Makes more sense with an Auto.

Well, a repo clutch switch is about $350. So you might be right....
