Hey all,

I'm trying to trouble shoot some fuel/electrical issues I'm having with a 92 RS 305 TBI.

On the drivers side firewall you will find two relays right behind the spark control module. Each relay has a four digit number.
One is 1227 and the other is 5311. One is hooked to a grey connector and the other is hooked to a black connector.

I need someone to look on thier car and tell me what number relay is hooked to which connector. I know one relay is for the fuel pump, but I have no clue as the what the other is for and I think mine might be mixed up.

Thanks

 

If you only have a single fan setup, the two relays are for the fuel pump relay (towards engine) and coolant fan relay (towards fender).

 

Thanks for the reply, the problem is, that I'm trying to figure out if I got the two relays mixed up. That's why I need to know which color connector goes to which relay.
