1983 Z28 retrofitted with a 87 IROC-Z 5.0L TPI, converting to the 90-92 Speed Density System. The Car will be a A/C delete system.


Having no luck looking through the Forums, can someone tell me where the location of the Secondary Cooling Fan Pressure Switch is located. I am working on my wiring harness to hook up the dual cooling fans but having no luck figuring out where this is.


Being a A/C delete system, I know I will have to ground the A/C Cooling Fan Pressure Switch, but what about the Secondary Cooling Fan Pressure Switch ?
