My owner manual does not ID the relays. From the schematic, I am pretty sure the gray relays are not the timer; they appear to be Neutral start, PTO safety start, ect. The yellow one appears to be for the turn signals.
I'm guessing it is one of those at the bottom of the picture. One is partially obscured by the wire harness.
