the big one on the right anyway. Im not sure what the smaller relay does. Anyway youre fuel pump relay is built into that.

i figured i needed that one but didnt know what it was. now i just need to figure the other two.

dual relay controls the fuel pump, power to the injectors, and power to the cold start and AAV.

single relay is for the injector cooling fan.

big black housing is a vacuum reservoir used with the later AC system. Not positive, but I am pretty sure this would not be used in a 1300 with or without AC

do you mean the cooling fan in the trunk that blows cool air onto the manifiold.? if so i wont need this relay.
im not using a 1300 anymore, this is for the 1500 out of same car. and im planning on using the ac. thanx again.

Somebody recently was asking about this, to smooth the vacuum signal from 2 DCNFs...
