Just tried out and it seem not to work. Althou, hope you try it.
I jumped on LFS again to see if relays are still working, and they does.
I'm thinking I made a mistake for wiring up relays for turn/hazard signals, because they are available in only one game - LFS.
On the other hand most games I play is from this camera view.
Is there any chance to activate bulbs (make them blink) with some button press while there is no need for ingame function activation? (working externaly w/o game)
This would make turn signals available for everygame, because in most cases people wont bother of them working in a game
****I conneted them to JC32 and made them as buttons.
