Ok. I'll try to make this as clear as possible. I am replacing my current electric fan setup on my 1932 ford roadster with a Cooling Components 1730 fan with shroud. My car is already wired/upholstered and currently is running haywire wiring kit with a 40amp relay built into the harrness to power the current fan. I know that the Cooling Components fans requires a 70amp relay and heavier gauge wiring. I have purchased a 70 amp relay kit from American Autowire. Now since the car is already completely wired and has upholstery finished I am wondering if I can wire this fan in another way to avoid taking out some of the insulation and upholstery on the firewall. I have created an image below that shows the American Autowire instructions on top and how I am planning on wiring this up. At this point I would really have 2 relays a 40amp that is already in the harness. Basically this would control the electric fan sender and hot wire coming out of the harness basically this would switch the pink wire on and off. I would have a constant ground to the main black wire. All that would then be running into the 70amp relay would be the main power coming from the battery cable side of the solenoid on the starter, pink wire coming from the harness, black ground wire and power supplied to the fan. Seems like all i am really doing is changing the switching system from the ground turning the fan on and off to the pink wire doing the switching on and off. Will this work ok? Thanks for all the advice in advance. Also I bought the fan and relay from Honest Charley since they are a HAMB alliance vendor. They were great to work with and had super fast shipping.
