Dos the Indicator Relay control front and back and where is it located
Attached is a link of the wiring diagrams that may help. Relay is likely next to fuse boxes. https://www.veikl.com/d/Ferrari-308-GTSi-GTBi-Technical-Electric-Education-Wiri-673/7
If you mean the flasher for the direction and hazard indicator lights on a 328 = yes, it does the all the flashing (front and rear and for the hazard function also). If any light is flashing correctly, the flasher is OK (and, if a front light is flashing OK, but a rear light is not, or vice-a-versa, the problem isn't the flasher). It's item 22 here (on the backside of the passenger footrest panel): https://www.ferrariparts.co.uk/diagram/ferrari/328-gtb-gts-(1985)/116-electrical-system-cables--fuses-and-relays
Thank you I like to change all my indicators to LEDs so in need to change the relay to stop hyper flash so I need to know the relay position that controls the indicators
