I am rewiring and replacing my fuse box that is in the engine bay. Based on the diagrams that are in the FSM the pin layout of the relay makes no sense, 1-3-4-5. Most micro relays are like the ones listed below, none are numbered like the relay in FSM. After figuring out the numbering I still need to translate it to your standard relay numbers like 30-85-86-87. Any help is appreciated.

Screenshot from FSM on the headlight and taillight relays.

I'm assuming this is from a 2G.

The FSM shows you both the functional and connector layouts with the example you showed. At the bottom of the page you would find the connector layou, for example here's A-14X

So you know that there is a power feed on the red wire going to pin 1 and a fat red wire to pin 5. Pin 3 has a normal sized red wire running off to additional circuitry. The relay's coil is between pin 1 and 3 and the relay is being used normally open with the common pin being #5 and the N.O. terminal being pin 4 with a large Red/Blue wire leading foot to fuses for the headlights and foglights.

All of that information came from that diagram. Note that for some reason on A-15X they swapped which side of the relay coil was "hot" but that doesn't change the way it works.

You should be able to mentally translate from the factory pinout to what you posted without any difficulty.

Wow, I don't know how I missed that diagram, it was at the bottom of the previous page. Thanks for this info.
