'79 308gt4 with air con fitted, the cabin fan resistor behind the passenger foot plate. What is the order of the three wires red/brown/blue? Image Unavailable, Please Login
Although I can’t help you with the wiring, On my ex GT4 I did away with the resistor and just wired the High speed fan via a relay.. The fan is insufficient as it is so I couldn’t possibly see the benefit of running it in either Low or Medium speeds. I actually tested the set up as it was in the Low, Medium and High speeds with an Anemometer and found running the High speed through a relay produced the most airflow..
