Toyota Repair: 94 camry relays, camry v6, rear defroster

Question
In the engine compartment on the left fuse box, there appears to be these 2 relays missing No. 1 fan relay and Main FR-DEF Relay, do I need to fill them in or is just just meant to be left unfilled? It's a 94 Camry V6, IMZ-FE engine. If so, needed please provide relay desc, part no. if apllicable. Already got the no.1 fan relay and it fit, but the picture for the Main ECU relay seems to be the right amount of pins ((5) but looks as if there horizontal in position rather than being vertical), the closest match i could find is a blower motor relay autozone part no. 36036 and/or 20006 (5pins vertical). Autozone nor the local toyota parts store can verify what the "Main FR-DEF Relay is". Already tried a Rear Defroster relay and theres not enough pins to match or correctly position it. What is this Main FR-DEF relay? if it' s even suppose to go in there? The car was impounded by the shady police or patsy police once, so i really don't know if someone took out some relays at the yard, I think the watchman said someone did take out a few relays?  I know u said it was a main relay, should i go ahead and see if that main relay fits in or go with the blower fan relay that appears to be the correct orientation of the pins lining in?  Does any of these sound to be the fit for what it says on the fuse relay housing "Main FR-DEF" Relay?

Answer
One end of the fuse box is triaght while the other is angled, the engine main relay has the 5 pins , for this, any relay that matches this configuratio and is rated at twelve volts and min 10A will work. At the other end is the EFI main relay which has 4 pins, both of these are needed to make the engine run. The #1 fan relay has four pins and is located opposite the main relay, it turns the cooling fan on. The MAIN FR DEF RELAY does not go into this fuse block.
I only show one defog relay in the relay/fuse block on the left of the dash where all the other fuses are.
