There are more than a couple relays in that location. Since it's been bobbed, I can only tell you what should be there.
There are two "round" relays on the bracket. Ignore them. They are for on board compressor and brake light relay.
There should also be two elongated relays. Ignore them also. One is the fuel pump relay, the other is the check relay for the low fuel warning indicator.
This should leave you with two "standard" looking square relays. They are for the turn signals, and the four ways. They are interchangeable. Try swapping them and see if you get your turn signals back.
