Hi guys,
since winter arrives shortly, I decided to do some major upgrades to my 66 Starfire. Thus, I also removed the engine. Now I have some questions about the electrical components on the firewall (which is what).
Can you advise me about the three devices shown in the picture? (only for no.2, I believe this is the heater motor relay, no. 1 and 3 seem to be some resistors but for what?)

Cheers, Steffen

P.S.: Sorry for the messy engine compartment, the previous owner installed a regulator in a shitty way, and I prepare to upgrade to a more powerful alternator with internal regulator (this is why the harness it taken out of its shell).

 

Item 1 is a circuit breaker for the A/C blower motor high speed relay (which is item2). The breaker is under the rubber cover.
Item 2 is the blower motor high speed relay.
Item 3 is a circuit breaker to feed power options like power seats or power windows

 

Thanks, Joe for the clarification! Item 1 was completely unclear to me. And also Item 3 (my car has power windows and the strato bench seat so the breaker makes sense).

ClassicOldsmobile is a great forum with you experts, learning every day when reading content or even getting my questions answered. Thanks so much!

Cheers & have a great week, Steffen
