i'm almost done with my 305TBI to 350TPI swap.i have two unkown relays plugs that should sit some where around the stock air box.
can you tell me what these relays are for?:rockon:

 

They are for the cooling fan relays. One sits right next to the radiator, the other sits over on the fenderwell by the coolant recovery tank.

 

damn that was a fast repsonce!
well since i'm wiring my fan to a switch i'm not going to need those relays.....right?

 

Depends on how you wire it. You may want to put the relays in there, and just switch them. The relays are pretty cheap, (bout nine bucks at autozone) and wiring the relays will be easier than trying to run a fat enough wire to handle the current draw of the fans.....

Have fun now.
