I am in the middle of installing a painless wiring harness, and also an electric fan with a thermo switch. The fan relay is wired to run on its own however there is a wire on the painless that hooks up to fan relay. my question is do they mean the grey wire on the switch or the orange wire marked ignition? thanks for any help here. Also can I run the ignition wire on the relay to the s terminal on my starter? Is the s hot only when the key is on or only while held to start position?
