Relay question (4 & 5 prong part links in post)

[Twglace]

Any one know what the two metal relays with 4 prongs and 1 small prong are for? They sit in front of the fuse box close to the battery... AND does anyone have a labeled picture of all of the relays... My car has a serious case of the gremlins...

Thanks!


P.s I'm also looking for locations of all the ground connections and the part#s for all of the straps.

Left one is the fuel pump (lift pump) relay. Right one is the main relay.

Get the ETM at wedophones, it is a map to chase gremlins, then check out the wire colors on the sockets and match the schematics. Otherwise you are hoping someone else's guess is correct. They are not labelled and they may not be in the same order on every car.

Would you happen to know what the part number is for both relays? I can't find any with the right 5th pin...
